The present application discloses a catalyst for producing ethylbenzene by gas-phase alkylation of ethanol and benzene in one step, in which the catalyst has a high alkylation reaction activity for the reaction and of ethylbenzene in the alkylation product. It has the characteristics of high selectivity, high hydrothermal stability, and stable reaction performance. The catalyst contains a TNU-9 molecular sieve in which mesoporous and microporous composites are used, and the silica-alumina molar ratio SiO 2 / Al 2 O 3 of the TNU-9 molecular sieve in which the mesoporous and microporous composite is 50 to 200. .. |
