Abstract

A hydrogenation-acid catalysis bifunctional catalyst, based on the mass of the catalyst, contains 80-99.8% of a silica-alumina molecular sieve component, 0.2-2% of a metal component with hydrogenation activity supported on the molecular sieve, and 0-20% of a hydrocarbyl modifying component. The hydrogenation active metal is selected from ruthenium, platinum, palladium, copper, nickel, or a combination thereof. The hydrocarbyl modifying component is a C1-20 hydrocarbyl. The catalyst has dual functions of hydrogenation and acid catalysis, and is suitable for benzene hydroalkylation reaction and alkane hydroisomerization reaction. It can be used in the benzene hydroalkylation to produce cyclohexylbenzene with high benzene conversion rate, high product selectivity, and less by-product cyclohexane.
