ABSTRACT:
Ethane is converted to LPG and gasoline and/or aromatics concentrate in a combination process which comprises directly passing olefin effluent from the thermal cracking of ethane over a special crystalline aluminosilicate zeolite of the ZSM-5 type and recovering aromatics and C.sub.3 + hydrocarbons. For best yields, the thermal cracking step is conducted under more severe conditions than are used when ethylene production is optimized. The second, olefin conversion step is carried out at either the same pressure as the cracking step or higher. The process is of particular interest where low cost ethane is available.
