에탄올의 탈수공정에 의한 에틸렌의 제조방법Process for producing ethylene by dehydration of ethanol

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 방법에 사용되는 장치의 개략도.1 is a schematic diagram of an apparatus used in the method of the present invention.

제2도는 다관형 반응기 배치도.2 is a multi-tubular reactor layout.

Claims (5)

알루미나규산염 촉매가 채워져 있는 고정상층을 가진 등온의 다관형 반응기에, 0.5―3LHSV의 속도로 에탄올을주입하면서 150―450℃범위의 반응온도와 0.1―100Psig의 압력하에 탈수 반응시킴을 특징으로하는 에탄올의 탈수 공정에 의한 에틸렌 제조방법.Ethanol characterized by dehydration at a reaction temperature in the range of 150-450 ° C. and a pressure of 0.1-100 Psig while injecting ethanol at a rate of 0.5-3 LHSV into an isothermal multitube reactor with a fixed bed layer filled with alumina silicate catalyst. Ethylene production method by the dehydration step of. 반응기 내부의 고정상층에 채워지는 촉매가 제올라이트 촉매임을 특징으로 하는 제1항에 의한 방법.The method according to claim 1, wherein the catalyst filled in the fixed bed inside the reactor is a zeolite catalyst. 여러개의 등온 다관형 반응기가 병렬로 연결된 반응기에서 반응시키되 최초에는 반응기중의 하나에 에탄올을 공급하지 않고 촉매활성이 저하된 반응기의 촉매를 교체할 때 가동을 중지시킨 반응기에 에탄올을 공급하여 탈수반응시킴을 특징으로 하는 청구범위 제1항 및 2항에 의한 방법.Multiple isothermal multi-tubular reactors were reacted in parallel reactors, but dehydration reaction was performed by supplying ethanol to the reactor which stopped operation when replacing the catalyst of the reactor whose catalytic activity was reduced without first supplying ethanol to one of the reactors. Method according to claims 1 and 2 characterized in that. 반응기로 주입되는 에탄올이 증기상태로 되어있음을 특징으로 하는 청구범위 제1항 내지 3항에 의한 방법.Process according to claims 1 to 3, characterized in that the ethanol injected into the reactor is in a vapor state. 반응온도가 300―400℃이고 반응압력이 3―20Psig임을 특징으로 하는 청구범위 제1항 내지 4항중의 어느 한항에 의한 방법.The process according to any one of claims 1 to 4, characterized in that the reaction temperature is 300-400 ° C. and the reaction pressure is 3-20 Psig. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
