Abstract:
1. A process for the conversion of solid biomass to hydrocarbons comprising: a. contacting said 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; b. separating said first product from said first biomass-catalyst mixture; c. charging said 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 said second product from said second biomass-catalyst mixture; e. charging said 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 said third effluent from said spent catalyst.
