摘要:
Solid biomass may be converted to hydrocarbons for use in renewable fuels uses by feeding biomass into a biomass conversion unit and pyrolyzing the biomass in the presence of a regenerated multi-functional catalyst. The regenerated multi-functional catalyst contains an acidic component, a basic component and a metallic component. The biomass is treated within the biomass conversion unit in at least two stages wherein at least one component of the regenerated multi-functional catalyst is fed into each of the stages.
摘要:
A two-stage reactor is disclosed for the conversion of solid particulate biomass material. The reactor is designed to maximize conversion of the solid biomass material, while limiting excess cracking of primary reaction products. The two-stage reactor comprises a first stage rector, in which solid biomass material is thermally pyrolyzed to primary reaction products. The primary reaction products are catalytically converted in a second stage reactor.

摘要:
A process and system for separating bio-gasoline, bio-diesel and bio-fuel oil fractions from a bio-oil, and for producing a renewable gasoline including at least in part the bio-gasoline fraction, is provided. The process comprises separating bio-oil into a bio-gasoline fraction and a heavy fraction based on their boiling points. At least a portion of the bio-gasoline fraction is directly blended with a petroleum-derived gasoline, without any prior hydrotreatment, to thereby provide a renewable gasoline composition.
