Abstract

The invention relates to a process for making ethylene by subjecting a gas mixture containing hydrocarbons, hydrogen, carbon monoxide, carbon dioxide and steam to a hydropyrolysis reaction. More particularly, the gas mixture is heated to temperatures higher than 800.degree. C. inside a reaction zone having metal walls. The walls contain aluminum and/or copper in at least their surface portions.
