The technology involves the oxidation of volatile substances on the surface of catalyst particles diluted with an inert material in a fluidized bed. The conventional use of quartz sand as an inert material leads to the accelerated degradation of the catalyst during on-stream use due to abrasion. This study is focused on the effect of the magnesium modification of active spherical Al2O3 and the development of a strengthened material (with crushing and abrasion strengths comparable to the values for a deep oxidation catalyst (DOC)) capable of minimizing DOC losses. The modified support is synthesized by impregnating spherical Al2O3 pellets with a precursor solution (nitrate and acetate) and subsequently calcining the pellets at 80°C. The resulting pellets are studied by X-ray fluorescence analysis (XRF), inductively coupled plasma optical emission spectroscopy (ICP-OES), low-temperature nitrogen adsorption (BET), and scanning electron microscopy (SEM). In addition, the mechanical strength of the pellets and their catalytic activity in CO oxidation are determined. It is found that the strength characteristics of Al2O3 linearly increase upon the introduction of magnesium in an amount of 2–9 wt %. The use of the selected material under laboratory conditions provides a threefold decrease in catalyst losses during 4.5-h abrasion compared with losses in the case of using quartz sand.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"17 1","pages":"66 - 74"},"PeriodicalIF":0.7,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117596","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}

APG aromatization is studied experimentally in a flow setup at a pressure of 0.1 MPa and temperatures of 450–600°C on ZnO/ZSM-5/Al2O3 catalyst. It is shown that the conversion of С3+ hydrocarbons is greatest in the 550–600°C range of temperatures to reach 22.7–27.8%, while the yield of aromatics is 8.8–10.9%. FT synthesis is studied on hybrid Co-Al2O3/SiO2/ZSM-5/Al2O3 catalyst at a temperature of 250°C, a pressure of 1.0 MPa, and GHSV = 1000 h−1. One liter of an experimental synthetic gasoline fraction is produced on a pilot setup to analyze its principal physicochemical properties and possible qualities of utilization. Calculations show that blending the gasoline fraction of FT synthesis with products of APG aromatization allows the octane number to be raised from 78.5 to 92.8 while the density grows from 710 to 778 kg/m3. The proposed engineering solutions can be used for converting APG into high-octane synthetic gasoline on modular Gas-to-Liquids (GTL) units.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"17 1","pages":"47 - 55"},"PeriodicalIF":0.7,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117597","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}

Optimum reaction conditions to provide the maximum rate of CO oxidation to CO2 have been determined, features of reaction kinetics have been found, and a mechanism has been proposed. It has been shown that systems based on a PdII aqua complex exhibit high activity and productivity; however, they have low stability and are used on stream only at a pH below 1.5. The stability of the catalyst can be increased by the simultaneous introduction of σ- and π-donor ligands into the system; however, the use of a PtIV complex in the presence of catalytic amounts of palladium salt in a ratio of 100/1 is more effective. Switching from HPA solutions with a low vanadium atom content (H7PMo8V4O40) to high-vanadium solutions of modified compositions (H10P3Mo18V7O84) provides an increase in the activity and productivity of the system, while the shapes of the kinetic curves and the general laws governing CO oxidation are preserved. The combined homogeneous PtIV + PdII + H10P3Mo18V7O84 catalyst remains stable during multicycle use without loss of activity, does not have an induction period in on-stream performance, and can be used at a pH of 0.7−2.5, which simplifies the hardware support of the process.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"17 1","pages":"21 - 30"},"PeriodicalIF":0.7,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117606","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}
