Basic Process Chemistry

−Conversion of solid fuels into combustible gas mixture called producer gas

(CO + H2 + CH4)− Involves partial combustion of biomass−Four distinct process in the gasifier viz.

• Drying • Pyrolysis • Combustion• Reduction

What is Biomass Gasification?

Gasification – Basic Process

ChemistrySchematic

Provides Energy that is

Green,

Clean,

Sustainable &

Convenient

at costs that enable all to use it

LPG versus CNG

mba@sngce

− Cost Effective

− Renewable

− Free of danger

− Uses natural wastes

− Eco-friendly

− Waste management

− High cost

− Nonrenewable

− Dangerous to use

− Uses organic products

− Not eco friendly

− Waste accumulation

CNG LPG

mba@sngce

Carbon emission is normal as comparedto the Earth’s Carbon cycle

Environment friendly

Clean, Efficient and Economical Uses raw materials like manure,

food wastes etc

Do not create waste

Good source of energy

Advantages of Bio-Mass

mba@sngce

The only negative aspect is the waste plant is too smelly. So in a tight and congested place it is not too good.

Disadvantages of Bio-Mass
