Exothermic methane coupling with ethylene as a hydrogen acceptor toward two-step methane conversion to ethylene

Abstract

Exothermic methane coupling with ethylene (ethene) as a hydrogen acceptor (2CH₄ + C₂H₄ → 2C₂H₆) was proposed as part of a two-step reaction that includes ethane cracking (C₂H₆ → C₂H₄ + H₂), which is a common industrial process, to provide methane conversion into ethylene as the net reaction (2CH₄ → C₂H₄ + 2H₂).
