Abstract
Thermochemical pretreatment is a key step in biotechnology for; converting lignocellulosic biomass to fuel ethanol and other valuable; chemicals. U.S. Department of Energy Biofuels Program researchers have; found that adding a Pressurized Hot Wash (PHW) step immediately; following pretreatment-while the pretreated material is still at high; temperature and pressure-significantly improves theoverall process.; The 'hot-washed' pretreated material can be more efficiently; digested by cellulase enzymes. Additionally, soluble lignins with potentially; valuable unique reactive properties are separated out.
