ABSTRACT:
To obtain an improved catalyst for fluid cracking purposes, kaolin or metakaolin is reacted with an acid of the group of phosphoric, sulphuric and acetic acids by mixing and heating to 25.degree.-110.degree. C., after which the slurry is washed. The slurry is not neutralized prior to washing. The thus obtained kaolin is then mixed with a crystalline aluminosilicate and, optionally, with a clay (e.g. kaolin), an active matrix and, as balance, a synthetic matrix, such as a silica, silica-alumina or alumina. The improved catalyst gives a better performance in terms of conversion and gasoline-yield.
