Abstract
A method for converting solid biomass into hydrocarbons includes contacting the solid biomass with a catalyst in a first riser operated at a temperature in the range of from about 50° C. to about 200° C. to thereby produce a first biomass-catalyst mixture and a first product comprising hydrocarbons; a) separating the first product from the first biomass-catalyst mixture; c) charging the first biomass-catalyst mixture to a second riser operated at a temperature in the range of from about 200° C. to about 400° C. to thereby produce a second biomass-catalyst mixture and a second product comprising hydrocarbons; d) separating the second product from the second biomass-catalyst mixture; e) charging the second biomass-catalyst mixture to a third riser operated at a temperature greater than about 450° C. to thereby produce a spent catalyst and a third product comprising hydrocarbons; and f) separating the third effluent from the spent catalyst.
