| Zusammenfassung: | The present invention relates to an ethylene production method using carbon dioxide and oxygen gas to prevent catalyst deactivation in an ethane dehydrogenation reaction, and in the ethane dehydrogenation reaction for producing ethane through the production method, it is possible to prevent deactivation of a catalyst due to change in oxidation number of chromium and sintering of chromium oxide, prevent carbon deposition and increase the yield of ethylene.
본 발명은 에테인 탈수소화 반응에서 촉매 비활성화 방지를 위해 이산화탄소 및 산소 기체를 사용하는 에틸렌 제조방법에 관한 것으로, 상기 제조방법을 통해 에틸렌을 제조하기 위해 에테인을 탈수소시키는 반응에서, 크롬의 산화수 변화 및 크롬 산화물의 소결에 의한 촉매의 비활성화를 방지하고 탄소 침적을 방지할 수 있으며, 에틸렌의 수율을 높일 수 있다. |
