Abstract:
A method for preparing aromatic hydrocarbons with carbon dioxide hydrogenation, comprising: directly converting a mixed gas consisting of carbon dioxide and hydrogen with the catalysis of a composite catalyst under reaction conditions of a temperature of 250-450° C., a pressure of 0.01-10.0 MPa, a feedstock gas hourly space velocity of 500-50000 mL/(h·g cat ) and a H 2 /CO 2  molar ratio of 0.5-8.0, to produce aromatic hydrocarbons. The composite catalyst is a mixture of a first component and a second component. The first component is an iron-based catalyst for making low-carbon olefin via carbon dioxide hydrogenation, and the second component is at least one of metal modified or non-modified molecular sieves which are mainly used for olefin aromatization. In the method, CO 2  conversion per pass may be above 33%, the hydrocarbon product selectivity may be controlled to be above 80%, the methane content is lower than 8%, C 5+  hydrocarbon content is higher than 65% and the proportion of the aromatic hydrocarbons in C 5+  hydrocarbons may be above 63%.

Claim (Index 11):
The method of  claim 1  wherein the content of the auxiliary in the iron-based catalyst is 0.5-10% of the total mass of the iron-based catalyst.
