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 ......
