PROCESS FOR PRODUCING SPHERICAL CATALYST PARTICLES, CATALYST PARTICLES AND THEIR USE IN A CHEMICAL SYNTHESIS

摘要

The process is used for producing spherical catalyst particles containing a zeolite as an active element according to which a sol containing zeolite crystals and at least one gel-forming compound is sprayed from below directly into a reaction zone containing a reaction gas such that the sol breaks up into individual sol beads immediately before or upon entry into the reaction zone, the sol beads flow through the reaction zone on a curved trajectory in so doing are pre-consolidated and the sol beads are collected on a collecting means. 10 claims
