Polyols and rigid polyurethane foams derived from liquefied lignocellulosic and cellulosic biomass

Liquefaction of lignocellulosic and cellulosic biomasses produces different polyol properties. Hence, direct comparative studies on the properties of both biomass liquefaction-derived polyols and polyurethane foams (PUFs) have been extensively performed. Optimization of oil palm empty fruit bunch fi...
