摘要

Composite catalysts consisting of Fe-Zn oxides and H-ZSM-5 were very effective for the selective production of aromatic hydrocarbons by CO2 hydrogenation. The ratios of aromatic hydrocarbons in all hydrocarbons were beyond 80 C-mol% using these catalysts. When the weight ratio of Fe-Zn oxide and H-ZSM-5 was optimized, the ratio of aromatic hydrocarbons reached more than 90 C-mol%. The Fe-Zn oxides acted as methanol synthesis catalyst in the composite catalyst, forming aromatic hydrocarbons by methanol-to-hydrocarbons reaction over H-ZSM-5. Two aromatic hydrocarbons, p-xylene and 1,2,4-trimethylbenzene, were mainly obtained by the shape selectivity effect of H-ZSM-5. The composite catalyst deactivated by coke formation could be regenerated by air flow treatment.
