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 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 silican, silica-alumina or aluminan. The improved catalyst gives a better performance in terms of conversion and gasoline-yield.
