BIOCORE 12-02-2014
● Continuous 1 kg/h lignin pyrolysis process demonstrated (ECN) ● Phenolic bio-oil (40-50%), bio-char (20-40%), gases (10-20%)
● 10% of phenol in PF resin
● Biochar in soil, coatings, bitumen, rubber
● Lignin pyrolysis is valid if higher value applications are considered
● Patent in preparation
● Status ● Ready for up-scaling
LIGNIN PYROLYSIS
BIOCORE 12-02-2014
● Eco-friendly lignin solvent fractionation process established (DLO) ● Narrow distributed fractions exhibit better performance in rigid foams
● Patent application in preparation
● Liquid polyols containing 30% lignin fulfil the require-
ments for use in polyurethane foams and films (IWC) ● Chemical modification needed
● Higher compressive strength
● High number of closed cells (>90%)
● Higher Tg, lower flammability, better UV stability
● Higher dimensional stability
● Status ● Upscaled sprayed foam produced
● Patent submitted (June 2013)
LIGNIN AS POLYOL IN PU
BIOCORE 12-02-2014
● Finely milled lignin can be used up to 15wt% in PU coatings (SYNPO)
● Rigid and flexible coatings ● Improved thermomechanical properties
● Higher electrical resistance
● Rigid self-levelling flooring systems ● Improved thermomechanical properties and abrasion resistance
● No positive effect on chemical resistance
● Status ● Good products achieved
● Patent submitted
LIGNIN AS POLYOL IN PU SYSTEMS
BIOCORE 12-02-2014
● Goal: substitute fossil phenol and formaldehyde (CHIMAR)
● Washed + milled lignin 80% substitution of phenol in lab scale panels
● 50% substitution of phenol in demo panels ● Passing exterior quality requirements
● Glyoxylated lignin ● 80% substitution of phenol and 28% substitution formaldehyde
● Glyoxylated lignin + tannin ● 100% phenol substitution
● Panel quality needs to be improved
● Status ● High substitution level achieved
● Up-scaling of wood panels
LIGNIN IN WOOD ADHESIVES
BIOCORE 12-02-2014
● Oxidation of lignin in acetic acid with homogeneous catalysts (ECN) ● About 50% of lignin is converted
● Molar mass reduced from 15kD to 1.5kD
● Limited production of monomers
● Mainly oligomeric carboxylic aromatics
● Limited product distribution
● Status ● Proof-of-principle achieved
● At R&D level
LIGNIN OXIDATION
BIOCORE 12-02-2014
● Polyoxometalate (H3[PMo12O40])-aided oxidation of lignin by H2O2
(IWC)
● Significant increase in functional groups (OH and COOH)
● Without degradation of lignin structure
● Modified lignin acts as an active filler
● Functionalization considerably improved lignin sorption capacity towards
heavy metals (e.g. threefold for Cd2+)
● Status ● A method for lignin functionalization was developed at bench scale
LIGNIN OXIDATIVE FUNCTIONALIZATION
BIOCORE 12-02-2014
● Organosolv fractionation of lignocellulosic biomass leads high purity
streams including lignin
● Organosolv lignin has high potential in added value market areas
such as building block in resins, coatings and foams
● Valorization of organosolv lignin in high value products is a key factor
for 2nd generation biorefineries
● The future for lignin is ......
