摘要

process for producing butanol from lignocellulosic feedstock, butanol and its plant. This invention relates to a process, a plant and butanol made of or derived from lignocellulosic feedstock. The process includes the depolymerization step of lignocellulosic material to form pentose and a residue. The process also includes the step of converting the pentose material to butanol and using the residue for power generation or other further downstream conversion.
