Title:
【発明の名称】カオリン含有流動クラッキング触媒
Document Type and Number:
Japanese Patent JP2966440
Kind Code:
B2
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 DEG -110 DEG 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 silica, silica-alumina or alumina. The improved catalyst gives a better performance in terms of conversion and gasoline-yield.
