Abstract:
A method for carbon dioxide direct hydrogenation to gasoline-range hydrocarbons is provided in this invention. Under the reaction conditions of 250-450° C., 0.01-10.0 MPa, 500-50000 mL/(h·g cat ) of feedstocks, 0.5-8 molar ratio of H 2  to CO 2 , the mixture of carbon dioxide and hydrogen may be directly converted to gasoline-range hydrocarbons over a multifunctional hybrid catalyst. The multifunctional hybrid catalyst comprises: iron-based catalyst for carbon dioxide hydrogenation as the first component, one, two or more of zeolites optionally modified by metal as the second component. In this method, a per-pass conversion of CO 2  may achieve more than 33%, the methane selectivity in the hydrocarbon products is less than 8%, the selectivity of gasoline-range hydrocarbons with carbon numbers from 5 to 11 in the hydrocarbon products is more than 70%. The obtained gasoline-range hydrocarbons exhibit high octane number due to its composition comprising isoparaffins and aromatics as the major components.

Claim (Index 4):
The method according to  claim 1 , wherein the zeolites are selected from the group consisting of ZSM-5, ZSM-22, ZSM-23, Y, Beta, MOR, MCM-22, and combinations thereof, and the metal is selected from the group consisting of Mo, Zn, Rh, Ru, Ga, Cr, Co, Ni, Na, Cu, Pd, Pt, La, and combinations thereof in the amount of 0.1%-20%.
