Sulfated zirconia containing acid catalyst and use thereof

摘要

A new bulk or supported catalyst containing a high proportion of crystalline sulfated zirconia and a hydrogenating transition metal for acid catalysed hydrocarbon conversion reactions. The catalyst has a surface area greater or equal to 135m<2>/g, preferably 150 m<2>/g, a pore vol. greater or equal to 0.16 cm<3>/g, preferably 0.20 cm<3>/g and a mean pore diameter greater or equal to 20 Angstrom , preferably 30 Angstrom . The crystallinity is quadratic or monoclinic and the apparent packing density is 0.5 - 3.0. The zirconia is partially or totally sulfated, the S content being 1 - 10%, preferably 1 - 5%, wt. relative to wt. of zirconia. Independent claims are also included for the preparation of the catalyst and its uses.
