Preparation method for ethylene using carbon dioxide and oxygen to prevent deactivation of the catalyst in ethane dehydrogenation

摘要

The present invention relates to a method for producing ethylene using carbon dioxide and oxygen gas to prevent catalyst deactivation in ethane dehydrogenation reaction. In the reaction of dehydrogenating ethane to produce ethylene through the production method, change in the oxidation number of chromium and chromium It is possible to prevent deactivation of the catalyst by sintering the oxide, prevent carbon deposition, and increase the yield of ethylene.
