1.Product description

The strong acid center B of the liquid-phase ethylbenzene synthesis catalyst is the active center of the alkylation reaction. Changes in acid strength have little impact on ethylene polymerization, but the B/L ratio has an important impact on the performance of the catalyst. Small catalyst particle size, well-developed pore structure, catalyst particle shape, larger average pore diameter, high pore volume, small zeolite grain size and the three-dimensional pore structure of zeolite all affect the activity, selectivity and stability of the catalyst. favorable。

2.Application description

The liquid phase ethylbenzene synthesis process uses a fixed bed, the reaction temperature is 150~300℃, the reaction pressure is 3.5-4.4MPa, the benzene/ene ratio is 2~15, and the ethylene mass space velocity is 0.1~4.4h-1.
