Abstract

본 발명의 촉매는 감마 알루미나 담체에 원소 기준으로 백금(Pt) 0.1-2중량%, 납(Pb) 0.1-1중량%, 알칼리 금속, 특히 칼륨(K), 나트륨(Na), 리튬(Li)중의 한 성분이 1.0-5.0중량%, 지르코늄(Zr) 혹은 텅스텐(W)이 백금 담지량의 1-50중량%을 함유하는데, 에탄, 프로판의 탈수소 반응에서의 활성 및 안정성이 현격히 개선되고 부반응에 의한 에탄, 프로판의 손실이 적은 촉매 성능을 발휘하도록 이루어지며, 또한 본 발명의 촉매 제조방법은 이미 잘 알려진 유적법에 의해 제조한 감마 알루미나 혹은, 분말 형태로 소성된 감마 알루미나를 담체로 사용하되, 먼저 최종 제조된 촉매의 납(Pb) 함유량의 50-99중량%을 함유한 용액을 담체의 제조시(졸-겔 법에 의해 담체를 제조할 경우 알루미나 졸을 형성할때, 침전법에 의한 경우 알루미늄을 형성 할때)에 혹은 미리 제조된 담체를 사용할 경우에는 타 금속 성분인 담지에 앞서서 담체에 함침하여 소성시키고, 나머지 용액(촉매 최종 납 함유량의 1-50중량%를 함유한 용액)은 백금의 담지 후에 함금법에 의해 담체에 담지되도록 한 것으로, 에탄, 프로판 및 에탄 프로판의 혼합기체의 탈수소 반응에서 활성 및 선택성이 높고, 장시간 사용에도 활성 및 선택도의 안정을 가진다.The catalyst of the present invention comprises 0.1-2% by weight of platinum (Pt), 0.1-1% by weight of lead (Pb), alkali metals, in particular potassium (K), sodium (Na), lithium (Li), on an gamma alumina carrier. One component of 1.0-5.0% by weight, zirconium (Zr) or tungsten (W) contains 1-50% by weight of platinum loading, the activity and stability in the dehydrogenation reaction of ethane and propane are significantly improved and The catalyst performance of the present invention is made to exhibit a low catalytic loss of ethane and propane, and the catalyst production method of the present invention uses a gamma alumina prepared by a well-known oil reclamation method or a gamma alumina calcined in powder form as a carrier. A solution containing 50-99% by weight of the lead (Pb) content of the final prepared catalyst is prepared during the preparation of the carrier (when the carrier is prepared by the sol-gel method, when the alumina sol is formed; Or a pre-made carrier In case of use, it is impregnated into the carrier prior to supporting other metal components and calcined, and the remaining solution (solution containing 1-50% by weight of the final lead content of the catalyst) is supported on the carrier by the plating method after supporting the platinum. It has high activity and selectivity in the dehydrogenation reaction of mixed gas of ethane, propane and ethane propane, and has stable activity and selectivity even in long time use.
