CATALYST AND METHOD OF PRODUCING UNSATURATED ALDEHYDE UNSATURATED CARBOXYLIC ACID |
摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to production of catalyst for producing unsaturated aldehyde and unsaturated carboxyl acid. Proposed method comprises applying catalyst powder coating on inert substrate to produce applied catalyst wherein inert substrate features ring shape and has outer periphery bent in longitudinal direction of substrate. Note here that catalyst is produced in atmosphere of granulating chamber at application of coating to ensure absolute humidity of 0.01 and higher. Catalyst thus produced is used for gas-phase oxidation of propylene, isobutylene, tert-butyl alcohol or methyl-tert-butyl ether to produce appropriate unsaturated aldehyde, or for gas-phase oxidation of said aldehyde to produce carboxylic acid.EFFECT: higher activity and friction stability at high yield of target product.4 cl, 9 ex |
