Abstract:
1. A process for the conversion of solid biomass to hydrocarbons comprising: a) contacting said solid biomass with a first catalyst stream comprising a catalyst in a first reaction zone operated at a temperature T b) downwardly passing said second biomass-catalyst mixture to a second reaction zone; c) charging a second catalyst stream to said second reaction zone for contact with said second biomass-catalyst mixture, wherein said second reaction zone is operated at a temperature T d) charging said spent catalyst to a regenerator wherein coke is burned off from said spent catalyst in the presence of oxygen thereby forming a regenerated catalyst; e) charging a portion of said regenerated catalyst to said first reaction zone as said first catalyst stream, and charging a portion of said regenerated catalyst to said second reaction zone as said second catalyst stream; f) upwardly passing said second gaseous product stream to said first reaction zone; and g) removing both said first gaseous product stream and said second gaseous product stream from said first reaction zone as a product mixture comprising hydrocarbons.
