Dehydrogenation Process

摘要

Disclosed herein is a process for dehydrogenating a hydrocarbon with a dehydrogenation catalyst comprising a step of activating the catalyst precursor in a H2-containing atmosphere. A particularly advantageous activation process includes heating the catalyst precursor to a temperature in a range from 400° C. to 600° C. The process of the present disclosure is particularly advantageous for dehydrogenating cyclohexane to make benzene.

主权项

1. A dehydrogenation process, the process comprising:
(1A) providing a catalyst precursor comprising (i) an inorganic support, and (ii) 0.01 wt % to 10.0 wt % of a first metal selected from the Groups 6 to 10 metals of the Periodic Table of Elements based on the total weight of the catalyst precursor; (1B) obtaining an activated dehydrogenation catalyst by treating the catalyst precursor at a temperature in a range from 300° C. to 600° C. for a period of at least 15 minutes in a H2-containing atmosphere; and (1C) contacting a first composition comprising cyclohexane with the activated dehydrogenation catalyst in a dehydrogenation reactor under a dehydrogenation condition to convert at least a portion of the cyclohexane to benzene and obtain a dehydrogenation reaction product.
