Myers, J W

A catalyst comprising a Group VIII metal selected from platinum, iridium, osmium, palladium, rhodium, and ruthenium supported on alumina is activated at an elevated temperature with a halosilane such as silicon tetrachloride. In a preferred embodiment, hydrogen is used in conjunction with the halosilane. In another preferred embodiment HCl is used in conjunction with the halosilane. The resulting catalysts exhibit an outstandingly high isomerization rate constant in the isomerization of feedstocks such as normal butane to isobutane. The catalysts are also well suited for hydrocracking. 16 claims.
