Abstract

The present invention discloses a catalyst and a process employing such catalyst for the dehydrogenation of paraffinic hydrocarbons, wherein the catalyst comprises a platinum group metal component, a zinc component and a magnesium component on a support comprising ZSM or borosilicate.

Description

Background of the invention [0001] The present invention relates to a method and catalyst for the dehydrogenation of hydrocarbons. More specifically, the present invention relates to a catalyst and an alkane dehydrogenation method using the catalyst. The catalyst includes a platinum group metal component, a zinc component and magnesium on a support component containing ZSM or borosilicate. Components, the method described is used to produce chemical raw materials. [0002] Propylene, also called propene, is a commercially valuable raw material used in the industrial production of polypropylene, acrylonitrile and propylene oxide. Now more than 95% of propylene is a by-product of olefin cracking and recovery. Propane dehydrogenation (hereinafter referred to as PDH) is another method of producing propylene. However, due to the relatively low conversion rate of propane, the previously known PDH method is limited in its application. [0003] The production method of dehydrogenation of ...
