Abstract: A process is described for producing a catalyst composition comprising an iridium component dispersed on a support. In the process, silica- o group to form an organic iridium complex on the support. The treated support is then heated in an oxidizing atmosphere at a temperature of about 325° C. to about 475° C. to partially decompose the organic metal complex on the support. The treated support is then heated in a reducing atmosphere at a temperature of about 350° C. to about 500° C. to convert the partially decomposed organic iridium complex into the desired iridium component.

Abstract: A cyclohexane dehydrogenation process comprising a step of providing, as a benzene-containing stream, a vapor phase in equilibrium with a liquid phase at a condensation separation system; supplying benzene, hydrogen, and cyclohexane into a dehydrogenation reactor where at least part of the benzene supplied is from the benzene-containing stream. The use of a condensation separation system enables the control of the partial pressure of benzene in the material fed into the dehydrogenation reactor by controlling the temperature of the vapor phase, and hence the control of hydrogen to benzene molar ratio in the dehydrogenation reactor. The process results in a long life of the dehydrogenation catalyst due to reduced coking.
