Based on studies of the hydrochemical characteristics of polluted rivers in urban areas (Khabarovsk, Russia) in the period from 1999 to 2019, it is shown that the ion concentration varies in a range of 0.005–0.7, 0.05–15, and 13–180 mg/L for ({text{NO}}_{2}^{ - }), ({text{NO}}_{3}^{ - }), and Na+, respectively. The kinetics of photooxidation of MB and MO is studied by optical spectrophotometry in a concentration ranges of the studied ions of 0–1–10–100–1000–10 000 mg/L using P25 titania as a photocatalyst. Photooxidation time (t) at different conversions (α) of the dyes at the initial (10%t), middle (50%t), and final stages (90%t) of the photocatalytic process is assessed. The effect of absorption of light quanta at wavelengths of 200–350 nm by Na+/({text{NO}}_{2}^{ - }) and Na+/({text{NO}}_{3}^{ - }) ions as a function of the concentration of these ions in a photocatalytic solution is shown. Recommendations for practical applications of the photocatalytic treatment of real contaminated water are given, while showing the necessity to take into account the concentration of the studied ions. A description of the observed effect of ions on the rate of photocatalytic oxidation of model organic dyes in terms of the band structure of semiconductors, elements of the theory of electrolytic dissociation, and recombination of free radicals in photocatalytic processes is proposed.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"16 3","pages":"350 - 362"},"PeriodicalIF":0.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254585","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}

The package of catalysts consists of catalyst pellets graded with respect to shape and size: segmented rings, hollow cylinders of two standard sizes, and pellets with a trilobe-shaped cross section. The tests are conducted in a trickle flow mode using a constant ensemble of microparticles—iron scale with a size of 5–150 µm—at the inlet of the package loading. It is found that the penetration coefficient of the package loading of guard bed catalysts does not change significantly (K ≈ 0.985) during the test. At the same time, the pressure drop across the 17-cm-high guard bed catalyst package linearly increases from 220 to 408 Pa due to the trapping of solid microparticles by the catalyst pellets.

The catalyst technology is tested on equipment at the Ishimbay Specialized Chemical Catalyst Plant (Russia). The resulting samples of industrial catalyst are studied via XRF, H2-TPR, and DTG, and tested in the synthesis of hydrocarbons from CO and H2 at 250°C, a pressure of 2.0 MPa, and a gas hourly space velocity of 1000 h−1. It is shown that the bifunctional cobalt catalyst for producing low pour-point diesel fuel under industrial conditions allows properties of the catalyst obtained under laboratory conditions to be reproduced. The technology for obtaining the catalyst can be recommended for the production of industrial batches. It is found that changing the conditions of the catalyst’s heat treatment and the presence/absence of a peptizer and pore former do not appreciably reduce the productivity of C5+ hydrocarbons. The amount of the diesel fraction in C5+ products obtained on industrial catalyst samples remains at the same level as on the laboratory catalyst sample. At the same time, the low-temperature properties of diesel fuel obtained on all catalyst samples have similar values. The best low-temperature properties of diesel fuel are obtained on an industrial sample synthesized without a peptizer and a pore-forming component. The cloud point and the point of liquid loss are −16 and −24, respectively.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"16 3","pages":"254 - 262"},"PeriodicalIF":0.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254579","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}

Although the activity of homogeneous catalysts in the FA dehydrogenation reaction is higher than that of heterogeneous catalysts, the use of the latter makes it possible to simplify the technology and improve the environmental safety of hydrogen production from FA. An increase in the efficiency of heterogeneous FA dehydrogenation catalysts based on noble metals (Pd, Au, Ag) is achieved by developing novel methods for synthesizing monometallic, bimetallic, and trimetallic nanoparticles on various supports. The review compares the efficiency of various heterogeneous nanocatalysts in the FA dehydrogenation reaction and discusses various factors (metal nature, nanoperticle size and composition, support nature) that affect the activity and hydrogen selectivity of the catalysts. A significant increase in activity in the FA dehydrogenation reaction is achieved by intensifying the interaction of metal nanoparticles with the surface of a chemically modified support, which contributes to a decrease in the size of nanoparticles, an increase in the uniformity of their distribution on the support, and a change in the electronic state of the metal. Advances in the development of industrial heterogeneous catalysts for the production of pure hydrogen from FA will provide a significant contribution to the development of hydrogen power engineering.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"16 3","pages":"339 - 349"},"PeriodicalIF":0.7,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254584","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}
