Multi-stage biocatalytic cracking process

摘要

Disclosed is a two-stage process for the catalytic conversion of a biomass feedstock. Upon establishing an intimate contact of the biomass feedstock with an inorganic catalyst material, the biomass-catalyst mixture is subjected to a first biocatalytic cracking reaction in a first biocatalytic cracking unit. Condensable product from the first biocatalytic cracking unit is separated from unconverted biomass material. Unconverted biomass material is subjected to a second biocatalytic cracking reaction in a second catalytic cracking unit. In general, the reaction conditions in the second cracking unit are more severe than in the first. In a specific embodiment the biomass feedstock comprises at least 10 wt% triglycerides.
