| 摘要 |
This invention refers to a process for the preparation of ethylbenzene from ethane and benzene. The process involves (1) contacting ethane in a dehydrogenation zone, with a dehydrogenation catalyst comprising a mordenite zeolite, optionally containing a metallic constituent selected from gallium, zinc, and platinum group metals, under reaction conditions that produce an ethylene stream diluted in ethane. The ethylene stream is subsequently contacted with benzene in an alkylation zone in the presence of an alkylation catalyst, such as an acid zeolite or a porous magnesium silicate, under such reaction conditions that ethylbenzene is formed.
