Abstract

Procedure for obtaining catalysts for the treatment according to the Claus reaction of waste gases, which also contain carbon sulfur derivatives, presenting a specific surface area at least equal to 80 m2/g and essentially consisting of active alumina and a titanium compound, which represent, counted in titanium oxide, from 1% to 60% by weight of the finished catalysts; characterized by comprising the steps of first impregnating supports consisting of active alumina with solutions of titanium salts, and then drying and calcining the product obtained from the first stage.
