Abstract:
A process for preparing an activated isomerization catalyst composition comprising the following steps:(a) preparing a composition comprising a Group VIII noble metal and an alumina carrier containing up to 20 wt % of other components,(b) optionally reducing the noble metal,(c) contacting the product of step (a) or (b) with a hydrocarbon-substituted aluminum compound, and(d) activating the product of step (c) by contacting the product of step (c) with a hydrogen-containing gas at a temperature above 500.degree. C., with the proviso that at least when the hydrocarbon-substituted aluminum compound present in the catalyst composition is not a hydrocarbon-substituted aluminum halide, the catalyst composition to be activated is contacted with a halogen compound either prior to or during the activating step,wherein the activated isomerization catalyst contains at least 2.5 wt % halide, based on the total weight of the activated catalyst.
