Description

TECHNICAL FIELD

[0001] The utility model relates to MTO catalyst technical field especially a kind of MTO catalyst filtering device. BACKGROUND

[0002] MTO catalyst refers to the catalyst used in methanol to olefins process, and the main component of MTO catalyst is SAPO-34 molecular sieve with three-dimensional 8-membered ring cross-channel, which has the characteristics of high and low carbon olefin selectivity. The performance of MTO catalyst has been verified in a circulating fluidized bed pilot plant, and it has the advantages of low abrasion, high activity, long service life, high diene and low coke formation rate.

[0003] When MTO catalyst is filtered, MTO catalyst needs to be mixed with other raw materials first. At present, manual mixing is used to mix MTO catalyst and raw materials, which leads to poor mixing efficiency, thereby affecting the subsequent filtration of MTO catalyst. In addition, the mixed raw materials need to be manually added to the filter cartridge when the mixed MTO catalyst is filtered, which also leads to poor filtration efficiency of MTO catalyst. Therefore, we propose a MTO catalyst filtering device to solve the above problems. UTILITY MODEL CONTENT
