PROCESS FOR PRODUCING A Si-BOUND FLUIDIZED-BED CATALYST, PARTICULATE FLUIDIZED-BED CATALYST OBTAINED THEREBY, USE THEREOF FOR NON-OXIDATIVE DEHYDROAROMATIZATION OF C-C-ALIPHATICS AND PROCESS FOR NON-OXIDATIVE DEHYDROAROMATIZATION OF C-C-ALIPHATICS

摘要

The invention relates to a process for producing a Si-bonded fluidized-bed catalyst for non-oxidative dehydroaromatization of C-C-aliphatics, the process comprising the following steps: I) forming an aqueous suspension comprising zeolite particles; II) adding a silicone resin mixture comprising one or more hydrolyzable silicone resin precondensates and mixing the aqueous suspension and the silicone resin mixture; III) spray drying the mixture obtained from step II, wherein the mixture is homogenized before the spray drying; and IV) calcinating the spray-dried fluidized-bed catalyst obtained from step III; V) applying a solution of a salt of at least one active metal selected from the group of Mo, W, Re, Ir, Ru, Rh, Pt, Pd and mixtures thereof to the calcinated fluidized-bed catalyst, wherein in step II at least one further Si-comprising binder selected from colloidal silica, a silica suspension and a silica sol. Further objects of the invention are a particulate fluidized-bed catalyst obtained by the process, use thereof for non-oxidative dehydroaromatization of C-C-aliphatics and a process for non-oxidative dehydroaromatization of C-C-aliphatics, wherein said catalyst is used. The technical result of the invention is improved abrasion resistance of the catalyst.
