摘要：
A catalyst is described for the preparation of isobutene by dehydroisomerization of n-butane consisting of a solid, granular support of porous gamma-alumina on the surface of which catalytic quantities of platinum, silica and preferably also one or more promotors are deposited. In a preferred form of embodiment this catalyst is used with a second catalyst which may be formed of Boralite B or a solid granular support of gamma-alumina on the surface of which catalytic quantities of silica are deposited. The present invention relates also to the process of dehydroisomerization of n-butane to isobutene in which the catalyst is used and the relative operating conditions.
