Abstract

The present invention provides a process for producing olefin having 3 or more carbon atoms from ethane stably in a simpler process. The present invention provides a method for producing olefin having a step of obtaining a cold fraction by cooling an ethane-cracked gas, which is obtained by thermal cracking of ethane in the presence of steam, to 600° C. or less; and a step of obtaining a catalytic cracking gas containing olefin having 3 or more carbon atoms by bringing the cold fraction into contact with a catalyst containing a medium pore diameter zeolite.
