Abstract
A method is disclosed for producing a mixture of CO and H2 (syn-gas). The method comprises contacting particles containing a coke deposit with oxygenated molecules derived from biomass. In a preferred embodiment the particles are catalyst particles. The method may be carried out in the regenerator of a conventional fluid catalyst cracking (FCC) unit.
Claims23
A process for converting biomass to reaction products, comprising:
- (a) contacting biomass with an inorganic material having catalytic properties, wherein said biomass comprises cellulose, hemicellulose, or lignin, wherein the inorganic material includes zeolite Y or ZSM-5, (b) converting the biomass to reaction products in the presence of the inorganic material, wherein the reaction products have a lower molecular weight than the biomass, wherein during at least a portion of step (b) coke is deposited onto at least a portion of said inorganic material thereby producing a coked inorganic material, wherein step (b) is carried out in a reactor vessel;
- and
- (c) providing at least a portion of said coked inorganic material and at least a portion of said reaction products to a regenerator vessel, wherein during at least a portion of step (c) at least a portion of said coke is removed from said coked inorganic material.
A process for converting biomass to reaction products, said process comprising:
- (a) contacting biomass with an inorganic material having catalytic properties, wherein said inorganic material comprises zeolite Y or ZSM-5, wherein said biomass comprises cellulose, hemicellulose, or lignin;
- (b) converting said biomass to reaction products in the presence of said inorganic material in a reaction vessel, wherein, during at least a portion of step (b), coke is deposited onto at least a portion of said inorganic material thereby forming a coked inorganic material;
- (c) separating at least a portion of said reaction products from said coked inorganic material thereby forming a separated quantity of said reaction products and a separated quantity of said coked inorganic material;
- (d) regenerating at least a portion of said separated quantity of said coked inorganic material in a regenerator vessel under conditions sufficient to remove at least a portion of coke from said coked inorganic material thereby producing a regenerated inorganic material;
- and
- (e) introducing at least a portion of said regenerated inorganic material into said reaction vessel.
