Abstract
The invention relates to a catalyst for the treatment of gases containing sulphur compounds, using the Claus reaction or using hydrolysis, which is made up of alumina-based porous particles and characterized in that the cumulative volume created by all the pores whose diameter is greater than 0.1 .mu.m, V.sub.0.1, is greater than 12 ml/100 g of catalyst and in that the cumulative volume created by all the pores whose diameter is greater than 1 .mu.m, V.sub.1, is such that the ratio V.sub.1 /V.sub.0.1 is higher than or equal to 0.65. This catalyst can be employed for the treatment of gases containing sulphur compounds by using the Claus reaction, or of gases containing organic sulphur compounds by using a hydrolysis reaction.
