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 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.

摘要： The present invention relates to a catalyst for the selective decomposition of cumene hydroperoxide, composed of zeolite crystals wherein a portion of the silicon atoms in the crystal lattice of silica is replaced by Al and B. The zeolite crystals are bonded to each other by a siliceous bonding agent which allows the catalyst to assume the shape of mechanically stable microspheres.The invention relates also to a process in which the catalyst is used, and to the related operating conditions.
