Dust collection of fine catalyst particles for paraffin dehydrogenation units using a standard TsN-15 cyclone and a new dust collector (NDC) with arc-shaped elements was studied. The results of numerical simulation of TsN-15 and NDC were presented. Comparative studies showed NDC to be more efficient than TsN-15 for trapping fine solid particles with sizes of less than 20 μm. The pressure and flow velocity profiles for NDC were shown to change as a regular tendency, without any critical deviations. The gas flow velocity through the arc-shaped NDC elements was shown to be stable in contrast to TsN-15, which creates high flow velocities at the cyclone periphery to increase the probability of dust breakthrough into the flow.</p>","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"14 4","pages":"369 - 375"},"PeriodicalIF":0.7,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4641634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent publications on the kinetics of partial oxidations of alcohols on silver were analyzed, including those that considered the use of a ring-shaped reactor to suppress the homogeneous decomposition stages of formaldehyde, the development of a new approach to process modeling taking into account different degrees of catalyst reactivity, and the creation of a simulator for calculating methanol oxidation based on a neural network using a genetic algorithm. The main stages of process development of partial oxidation of ethylene glycol to glyoxal on Ag catalysts are briefly described.
