Preparation process of catalysts and catalysts additives and a catalyst or catalyst additive and the use thereof

Kneading and / or a suspension containing a catalytically active component, preferably H-ZSM-5 zeolite, aluminum hydroxide and / or one or more hydroxide compounds and / or one or more coupling agents, preferably kaolin (it) and one or more habit suppressing agents. or less than 1 of the following, y and z instead of kaolin (it) or a part thereof as a filler, which consists of grinding, spray drying and heat treatment; If x is 0.4, 10 or 16-18, the formula is H4 + yz [(SiO4 / 2) x -y (AlO4 / 2) y (SiO3 / 2O) 4-z (AlO3 / 2) z], one or more It relates to the process for the preparation of catalyst or catalyst additives, which involves the use of aluminum-containing silicic acid modification. Process and catalyst or catalyst additives make it possible to increase the butane part of the separated product.
