Katalysatorbærer på grundlag af et metaloxid fra det periodiske systems gruppe IVB samt dens fremstilling og anvendelse

摘要

The invention proposes alternatives to alumina-type catalyst supports, based on zirconia or titania with silica, which are f to have a higher activity. A catalytic support comprises mainly a metal oxide of group IVB with the incorporation of silica, the weight ratio of IVB o to silica being between 5 - 70. The group IVB oxide is crystalline in form, and the surface area is greater or equal to 160 m<2>/g. Independent claims are also included for catalysts supported on the material and the preparation of the supports and their
