【Abstract】 The industrial application of a new process and catalysts developed by Research In-stitute of Petroleum Processing for benzene alkylation with ethylene in liquid phase was carried on the styrene unit in Yanshan Petrochemical Company. The result showed that both alkylation and transalky-lation catalysts possessed good activity, selectivity and stability. In alkylation reaction, the ethyl-ben-zene selectivity was higher than 86.5％;the ethylation selectivity was approximately 100％;and the ethylene conversion was 100％. In transalkylation reaction, both ethyl-benzene and multi-ethyl-benzene conversions were more than 79％; and ethyl-benzene selectivity was near 100％. The process has the advantages of simple flow scheme, convenient operation and high quality and high yield of ethyl-benzene product. The said process is different from the AlCl₃ process, it is a clean process which does not need any special wastes treatment.更多还原
