Abstract: With α-MS，hydrogen as raw material，cumene was synthesized by catalytic hydrogenation in a trickle-bed. The work mainly investigated the influence of reaction temperature，pressure，circulation，feeding α-MS concentration，hydrogen oil ratio on hydrogenation reaction. The results showed that the reaction temperature can accelerate the reaction rate within the range of 60—120 ℃；hydrogenation reaction rate is the fastest with the pressure from 0.7 to 0.8MPa，processing capability is the largest；the improvement on hydrogen to oil ratio ensure raw materials and catalyst contact time under the premise of the reaction；the circulation rate and the concentration of the feed α-MS reaction rate can be changed but the actual processing capacity cannot be changed；the stability of catalytic activity is the premise of the hydrogenation. The constrains for bed design processing capacity is the key for the reduction of current hydrogenation effect and the limitation of production capacity.
