Abstract:

The oxidative coupling of methane (OCM) to ethylene is a promising alternative for the oil based industry.

In this process, beside the valuable product ethylene, unwanted by-products like CO₂ are produced.  The gas stream, therefor, has to be refined further. The process is not applied in the industry yet, because of high separation costs. The focus of this article is on the CO₂ purification of the OCM product stream.
