PROCESS FOR PREPARING A CATALYST SUITABLE FOR USE IN ISOMERISING HYDROCARBONS, THE CATALYST THUS OBTAINED, AND ITS USE

摘要

The invention pertains to a process for preparing an activated catalyst composition in which a catalyst composition comprising a Group VIII noble metal and a hydrocarbon-substituted aluminium compound on an alumina carrier containing up to 20 wt.% of other components is activated by being contacted with a hydrogen-containing gas at a temperature in excess of 500 DEG C, with the proviso that at least when the hydrocarbon-substituted aluminium compound present in the catalyst composition is not a hydrocarbon-substituted aluminium halide, the catalyst composition to be activated is contacted with a halogen compound either prior to or during the activating step. The catalyst obtainable by this process and the use thereof in hydrocarbon conversion processes, such as isomerisation and alkylation processes, are also part of the present invention. The effect of the high-temperature activation step is that the activity of the thus obtained catalyst is improved in comparison with a catalyst of the same composition which has not been subjected to said high temperature activation step.
