CATALYST CARRIERS, A PROCESS FOR THEIR PREPARATION, AND THEIR USE IN MAKING CATALYSTS FOR THE CONVERSION OF HYDROCARBON CHARGES

摘要

Catalyst carriers being an intimate mixture of aluminum oxides and at least one second metal from groups VIa to VIII of the periodic table of the elements; preparation process of said carriers by coprecipitation in the form of a gel from aqueous and/or organic solutions of aluminum and the second metal, followed by drying and calcination; and the use of these carriers in the making of catalysts, particularly for the conversion of hydrocarbon charges or desulfurization thereof.
