Abstract
The present invention relates to a process for the production of ethylene, comprising the following steps of: (a) thermally converting a feed charge containing methane into acetylene as an intermediate, (b) in-situ hydrogenation of the acetylene produced in step (a) into ethylene by a non-catalytic hydrogen transfer mechanism, characterized by (c) recovering heat from hot effluents obtained in step (b) which may be utilized for different purposes.

A process for the production of ethylene, comprising the steps of:
- (a) thermally converting a feed charge containing methane into an acetylene containing effluent,
- (b) in-situ hydrogenating the acetylene produced in step (a) into ethylene characterized in that the hydrogenating is carried out by a non-catalytic reaction by intimately mixing the acetylene containing effluent with an ethane feed, and
- (c) recovering heat from hot effluents obtained in step (b) and utilize these for different purposes.
