摘要： The disclosure is concerned with a high temperature stable catalyst comprising an alumina base support and a catalytically active component supported on the support. The support is featured by its specific composite oxide having a specific surface area of at least 10 m 2 /g and a structural form of amorphous state or a phase resemble to lanthanoide β-alumina. The composite oxide can be converted to lanthanoide β-alumina when heated to an elevated temperature above 1000° C within 2 hours. The composite oxide is substantially free from such ingredients as accelerate grain growth of alumina. The ingredients are for example Cr, Sr or Ce. The present disclosure is also concerned with a process for preparing the catalyst and a process for conducting chemical reactions such as steam reforming, desulfurization of heavy oil, cracking of hydrocarbons, etc. using the catalyst.

摘要： This invention relates to a process for the production of unsaturated compounds by dehydrogenation of a corresponding saturated compound in the fluid phase in the presence of a supported gallium compound as catalyst. The support is a tectometallosilicate which has the following composition in terms of the mole ratios of the oxides:
and is suitably the zeolite Theta-1. The catalyst composition may be subjected to a thermochemical treatment prior to contact with the saturated compound to be dehydrogenated.
