FROM CHEMICAL & ENGINEERING NEWS SEPTEMBER 19, 2016 NOW BOARDING: COMMERCIAL PLANES TAKE FLIGHT WITH BIOBASED JET FUEL

This year, renewable jet fuel took off, graduating from demonstration and test flights to some regular commercial use. In January, some flights left the airport in Oslo, Norway, running on jet biofuel produced from an oilseed crop. In March, United Airlines became the first U.S. airline to use biofuel for regularly scheduled commercial flights leaving Los Angeles International Airport. Three months later, Alaska Airlines flew commercial flights using biofuel produced from renewable isobutyl alcohol.

By 2050, the global aviation industry aims to combat climate change by reducing net carbon emissions by 50% compared with 2005 levels. That’s a commitment to cut one-tenth the emissions projected for 2050. Improved engine efficiency and aircraft aerodynamics will provide some reductions. But transitioning to fully renewable jet fuel is key to meeting the targets suggested by the International Air Transport Association (IATA). Alternative energy sources considered for cars and trucks—things such as batteries, fuel cells, or liquefied hydrogen—would be technically impossible for planes or require too much infrastructure change in the global aviation industry to be practical.

Companies develop jet biofuels to chemically mimic petroleum-derived jet fuel so they can be used immediately with existing engine designs and fueling infrastructure. But the industry is far from supplying the more than 300 billion L of jet fuel used worldwide just in 2012. For example, United has a contract to purchase 57 million L of renewable fuel over the next three years. Only two companies produce renewable jet fuel on a commercial scale, and airlines have already claimed all the jet biofuel to be produced from three future plants. For



now, fuel producers lack the funds, policy support, and renewable fuel incentives to build more factories and increase production volumes, though there are signs that the industry is ready to grow.

“In the future, we imagine all jet fuel having some level of renewable content,” says Steve Csonka, executive director at the Commercial Aviation Alternative Fuels Initiative, a group of airlines, airports, aircraft and engine manufacturers, researchers, and U.S. government agencies.

The development of aviation biofuels lags about a decade behind the first biofuels for cars and trucks, a delay that has provided the jet fuel industry a chance to learn from previous mistakes. For instance, revised emissions estimates for first-generation biofuels—corn ethanol blended with gasoline and fatty acid methyl esters added to diesel—reveal that they may not be as green as they first seemed: Converting land to grow crops for biofuel releases carbon dioxide trapped in the soil, making the greenhouse gas impact for corn ethanol and biodiesel potentially greater than their petroleum-derived counterparts.

In general, jet biofuel producers look to make renewable fuels that deliver about 50 to 80% net greenhouse gas reductions, Csonka says. To do this, they extract oils from nonfood crops such as camelina and jatropha grown on nonarable land or in rotation with grains. Companies also use waste products—such as animal fat, used cooking oil, forestry and agricultural waste, and household trash—as feedstocks. Having a variety of feedstocks makes it easier to produce renewable jet fuel around the world because refineries can use the feedstock most available in their region, says Robert Boyd, manager of the biofuel deployment program at IATA.

Currently, feedstocks can be converted to jet biofuel through one of five different processes approved by ASTM International, a nonprofit group that develops international technical standards for materials and products. Each process, however, makes only some of the hydrocarbons found in petroleum-based jet fuel, which contains aromatic compounds along with linear, branched, and cyclic paraffins—saturated hydrocarbons containing eight to 16 carbon atoms. This mixture creates a fuel with the lubricity, freezing point, and energy density, among other specified properties, that keep it from boiling, freezing, or absorbing water in the variety of conditions a plane experiences on land or in the air. Gasoline and diesel have physical properties unsuitable for airplanes: The shorter hydrocarbons in gasoline can make the fuel too volatile, whereas the longer hydrocarbons in diesel can increase the fuel’s freezing point.

Neste, in Finland, and AltAir Fuels, in California, the two firms capable of making jet biofuels at commercial scale, use animal fat, plant oil, and used cooking oil to produce primarily linear and branched paraffins. To convert fat and oil to hydrocarbons, the companies first deoxygenate and hydrogenate them to make long, linear hydrocarbons, which are then cracked and isomerized to shorter linear and branched C8 to C16 hydrocarbons. This so-called hydroprocessed esters and fatty acids (HEFA) process is also used to produce renewable diesel that is chemically indistinguishable from petroleum-derived diesel.

Because current aviation biofuels contain only linear and branched paraffins, they have to be blended with petroleum-derived fuels to create a jet fuel with the physical properties specified by ASTM. The renewable fuel at Oslo Airport contains 50% biofuel produced by Neste, and United uses renewable fuel containing 30% biofuel from AltAir Fuels.

Over the next three years, AltAir Fuels will deliver about 37% of its 150-million-liter yearly production capacity for renewable fuel to United; most of the rest of the company’s capacity will go toward producing renewable diesel. Neste, in Finland, produces 2 million L of renewable diesel, gasoline, and jet fuel each year.

In Minnesota, Gevo produces renewable jet fuel on a demonstration scale using isobutyl alcohol produced from fermenting cornstarch. The company provided fuel to Alaska Airlines for its test flights in June.

The first step in this process, called alcohol-to-jet, involves dehydrating isobutyl alcohol to form isobutylene, then oligomerizing isobutylene and hydrogenating the resulting compounds to yield mainly C12 and C16 branched hydrocarbons. According to guidelines set by ASTM, a renewable fuel can contain up to 30% of this fuel. Researchers at Washington State University are working on incorporating feedstocks other than cornstarch into this process, for example, sugars from wood waste fermented into alcohols.



A different alcohol-to-jet pathway starting with ethanol rather than isobutyl alcohol could create fuel that does not need to be blended, says Richard Hallen, a staff scientist at Pacific Northwest National Laboratory. That’s because starting with a two-carbon alcohol rather than four-carbon isobutyl alcohol enables scientists to build a wider range of hydrocarbons instead of being restricted to a handful of longer ones, as is the case for current jet biofuels. To simplify the ASTM certification process for this production pathway, companies are first working to transform ethanol to branched saturated hydrocarbons using the same strategies used in the approved isobutyl alcohol route.

At a demonstration-scale jet biofuel plant in Georgia, LanzaTech collects a mixture of carbon monoxide and hydrogen called syngas from industrial exhaust streams. Microbial fermentation of the syngas yields ethanol that is dehydrated to ethylene, then oligomerized and hydrogenated to form branched C10 to C16 paraffins.

ASTM is assessing this ethanol-to-jet pathway for official approval, a process that can take at least five years, Hallen says. Other companies are developing aviation biofuel that can be used without blending, as well as other fuels containing cyclic paraffins and aromatics that could be mixed with current jet biofuels to provide a fully renewable fuel. But the lengthy certification process slows the growth and commercialization of these processes.

In the next two years, three more commercial-scale jet biofuel plants are expected to open in the U.S., all supported by federal funds. Each plant will construct linear and branched hydrocarbons from syngas using a series of reactions called the Fischer-Tropsch process, although the factories will use different feedstocks. Red Rock Biofuels will gasify wood waste, Emerald Biofuels uses oil from nonfood crops, and Fulcrum BioEnergy will gasify municipal solid waste. Though these refineries are not open yet, airlines already anticipate the fuel: Cathay Pacific, an airline based in Hong Kong, has agreed to purchase 1.4 billion L of fuel produced by Fulcrum over 10 years. United has also invested $30 million into the company. Southwest Airlines and FedEx have agreed to purchase fuel produced by Red Rock.

Despite the demand and airline support for jet biofuel, producers struggle to make renewable fuel cost-competitive with petroleum-derived fuel. Fuel is already the second-largest operating expense for aviation, and renewable fuels can cost 40–75% more than petroleum-derived fuel, depending on the production process and current price of traditional jet fuel. Lacking blending mandates for renewable jet fuel, companies have fewer reasons to produce more costly jet biofuel when they could use the same feedstock or process to generate renewable ethanol or diesel, both of which are supported through 2016 by U.S. Environmental Protection Agency renewable fuel mandates. “When trying to develop a new market, there needs to be some incentives to get people and companies committed to developing the technologies to commercial scale,” Hallen says.

To reduce production costs, some companies repurpose existing infrastructure, as AltAir Fuels did when it retrofitted an existing oil refinery near the Los Angeles airport. They also look for feedstocks available near a refinery, to save collection and transportation costs. And by only considering processes that provide at least 50% net greenhouse gas reductions, companies position their fuels to be eligible for future renewable fuel subsidies, Csonka says.

Current policy support for jet biofuels includes targets for renewable aviation fuel from the U.S. and the European Union, along with the U.S. military, though the biggest push for sustainability comes from the aviation industry itself. At the end of this month, the International Civil Aviation Organization, a United Nations group that adopts standards and recommendations for international aviation, will meet to set the next level of emissions targets and global sustainability measures for the aviation industry, including clarifying the role of jet biofuels in meeting those targets. One country, Indonesia, has set a jet biofuel blending mandate by 2018.

More than 2,500 commercial flights have flown using renewable fuel already, and the number is growing. Research, demonstration, and commercial projects are ongoing worldwide. And, Csonka says, “over the next several years, more refineries, feedstocks, and production pathways will appear, showing that the area is moving toward broader commercialization.”

ACS KIDS AND CHEMISTRY AT THE GREEK FESTIVAL, DOWNTOWN COLUMBUS By Jeffrey Trent, Columbus Section Chair

The ACS Columbus Section Chair donated 36 volunteer hours over three days to the Greek Festival over the Labor Day Weekend, Friday, September 2nd through Sunday, September 4th – Great Chemistry Everywhere! Hope all of you had a wonderful Labor Day! The ACS Columbus Section, in a bid to recruit the youngest of scientists, provided an ACS Kids & Chemistry booth in downtown Columbus as part of the 44th annual Greek Festival. The ACS Columbus Section was invited to participate for the second year by Mark and Penny Slaiman, coordinators of the children’s activities for the Greek Festival. Mark is an ACS member and a colleague of ACS Chairman Jeff Trent. Both work at West-Ward Pharmaceuticals in Columbus, Ohio. The featured molecules were the ball and stick models:

+ =

We wanted to show that glucose (blood sugar) and fructose (fruit sugar) are components of the ordinary white sugar (sucrose) found in the kitchen. See the six-membered ring and the five-membered ring? Even though glucose and fructose have the same formula, C6H12O6, we can still identify them by the ring structures: six = glucose and five= fructose. The other featured molecule was beta-carotene; the orange pigment in carrots:

This was shown as a very long ball and stick model. See the symmetry and the ring structures on the ends? Also note the alternating single and double bonds. Even our younger visitors could see the pattern of rings and single and double bonds and feel they knew something about organic chemistry. Naturally we made things bubble, smoke, and change colors to add a little excitement. Carbon dioxide as dry ice creates clouds in a fountain, in soap bubbles, and in a 500-mL graduated cylinder. The solution in the graduated cylinder changes colors as carbon dioxide goes into solution forming carbonic acid, CO2 + H2O -> H2CO3. For effect, a robot holds the graduated cylinder as a platform for this chemistry. Children collect overflowing bubbles in their hands, watching as the popping bubbles release water vapor clouds. Universal indicator shows the presence of carbonic acid. Windex, as our ammonia base, is added to water with universal indicator giving a nice, deep, purple color. Dry ice was added. Bubbles and smoke plus flashes of blue, green, yellow, and light orange appear as the carbonic acid is formed. We also shared alternate energy sources: wind power, solar power, hydroelectric power, mechanical power, and chemical power. Table top wind turbine generator, solar voltaic panel energizing toys, a water turbine model in the fountain, wind-up mechanical toys, and finally, chemical energy from a voltaic pile (D-cell batteries) is used to run a homemade flashlight. Science is Fun! Mark Slaiman and Jeff Trent presented demonstrations in the Kids& Chemistry Booth for three days with Greek Festival volunteers, Bilinda Allan, and three enthusiastic teenagers.



The Annunciation Greek Orthodox Cathedral 555 N. High Street, Columbus, Ohio 43215

ACS Columbus Section Chair – Ready to Share Great Chemistry Everywhere! – Including the Greek Festival (long after philosophers, scientists, and mathematicians like Plato, Socrates, Archimedes, Pythagoras and other Greek heroes).

ACS member Mark Slaiman prepares to present Kids & Chemistry demonstrations.

We had tremendous response from parents looking to keep children occupied at the rainbow fountain. Teens and adults appreciated our molecule collection as well as being cooled off by our dry ice “air conditioner” as we blew a stream of cold, condensed water vapor from a vacuum flask chilled by the -78°C (or -103°F) frozen carbon dioxide sublimation in water.



ACS Kids & Chemistry at the Greek Festival - Thank You! Dear Jeff- On behalf of the Greek Orthodox Cathedral, I want to thank you for the stewardship you shared with our church this past weekend. Your science demonstrations and enthusiasm ignited imagination, excitement and pure joy. From simple machines and technology to compound magic, the Columbus community kids experienced a new world of learning. Since the Greeks are known for their early scientific achievements this program is a great fit for us and our festival. More importantly, you took the fear of science away- and made science accessible. I did hear from some of the kids that they wished you were their science teacher and that now, they will consider their school science fairs more seriously. I know that your program may have opened new career opportunities- but I also believe that you may have helped them see science is everywhere. You helped them learn to ask why and that is a life skill we all need in this world. I would recommend your exhibit and demonstration to any organization that services the learning and care for children. Your personality and joy is contagious. I, only wish I had more time to spend in that booth. I cannot wait till next year when maybe my new set of godchildren and grandchild can come and experience science at the Greek Festival if you would consider returning Labor Day weekend 2017. Again- thank you so much. If we can be of assistance to you in any way, please let us know. Much continued success to you- Helen Rankin Sunday School Director Festival Children's Area Coordinator
