摘要:
The invention relates to a process for producing a particulate, Si-bonded fluidized-bed catalyst having improved abrasion resistance, which comprises the steps I. provision of an aqueous suspension comprising zeolite particles, II. addition of a silicone resin mixture comprising one or more hydrolyzable silicone resin precondensates and mixing of the aqueous suspension and the silicone resin mixture, III. spray drying of the mixture obtained from step II, with the mixture being homogenized before spray drying, and IV. calcination of the spray-dried fluidized-bed catalyst obtained from step III, and an Si-bonded fluidized-bed catalyst which can be produced by this process and also its use for the nonoxidative dehydroaromatization of C1-C4-aliphatics.
