Process for producing a fuel and byproduct from biomass or biomass derived material

摘要

The present invention provides a process for producing a fuel and a byproduct from biomass or biomass derived material. The invention comprises providing a processed biomass feedstock and carrying out or causing one or more parties to subject the processed biomass feedstock to gasification to produce carbon monoxide and hydrogen and cresylic acid and recovering the cresylic acid or a portion thereof. The processed biomass feedstock may be co-gasified with coal. The hydrogen from the gasification may be recovered or the carbon monoxide and hydrogen may be further reacted to produce a fuel or fuel intermediate. One or more products obtained from the process are provided, for use as, or to produce a transportation or heating fuel. The invention may allow for advantaged fuel credit generation.

1. A process for producing a fuel and a byproduct from biomass or biomass derived material, said process comprising the steps of:
(i) providing a processed biomass feedstock for use in gasification; (ii) carrying out or causing one or more parties to carry out a gasification process comprising:
(a) subjecting the processed biomass feedstock to gasification to produce a product comprising carbon monoxide and hydrogen and cresylic acid, wherein the processed biomass feedstock is co-gasified with coal, and wherein the gasification is conducted in at least one Lurgi-type bed reactor;(b) recovering at least a portion of the cresylic acid and providing a chemical product comprising the recovered cresylic acid;(c) recovering the hydrogen produced or derived from step (ii)(a) or further reacting the carbon monoxide and hydrogen to produce a fuel or fuel intermediate;(d) providing one or more products obtained from step ii(c), for use as, or to produce a transportation or heating fuel; and(e) generating or causing generation of a renewable fuel credit.
