Abstract
A green process and system are disclosed for utilizing a biomass filter aid in the filtration of a bio-oil. The process comprises filtering a bio-oil containing residual solids from a conversion reaction in the presence of the biomass filter aid to produce a filtered bio-oil. The biomass filter aid facilitates efficient removal of residual solids from the bio-oil. The spent biomass filter aid containing the residual solids may be recycled as a conversion feedstock or used as a combustion heat source in the biomass conversion system.
Claims13
A biomass conversion system comprising:
- a biomass feedstock source for providing solid particulate biomass;
- a splitter coupled to said biomass feedstock source and operable to split said solid particulate biomass into a biomass feedstock fraction and a biomass filter aid fraction;
- a conversion reactor for thermally converting said biomass feedstock fraction into an initial conversion product;
- a residual solids separator for removing residual solids from at least a portion of said initial conversion product, wherein said residual solids separator comprises a porous filter element comprising an inlet side and an outlet side, wherein said inlet side is capable of retaining and supporting said biomass filter aid fraction thereon;
- a biomass feed system for transporting said biomass feedstock fraction from said splitter to said conversion reactor;
- and
- a biomass filter aid transport mechanism for transporting said biomass filter aid from said splitter to said residual solids separator.
