First Claim
Patent Images
1. A process for producing butanol from lignocellulosic feedstocks, wherein the lignocellulosic feedstocks include cellulose, hemicellulose, and lignin;
- the process comprising;
depolymerizing pentose from hemicellulose in a lignocellulosic feedstock to form a remainder, wherein the remainder comprises cellulose and lignin;
converting the pentose to butanol;
depolymerizing hexose from the cellulose in the remainder without competing with pentose consumers; and
consuming the remainder to produce energy.

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