Catalyst samples were synthesized from platinum, palladium (as active metals), and heat-resistant high-silica glass fibers, both unmodified and modified with Zr. Catalysts are prepared via surface thermal synthesis and leaching with impregnation. All three tested samples show approximately the same activity, but Pt-based STS is preferred because it uses a much cheaper and widely available glass fibers instead of rare and expensive Zr-modified materials. More than 200 h of life tests for this catalyst show its high stability. The rate of hydrogen oxidation on this catalyst can be described by a kinetic equation corresponding to the law of mass action with a linear dependence on the pressure in the reaction system. The studied GFC can be made in the form of structured cartridges with a small drop in pressure and high intensity of heat and mass transfer under the conditions of the industrial technological process, so its future practical application seems promising.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"15 1","pages":"1 - 5"},"PeriodicalIF":0.7,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4909289","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 characteristic patterns of interaction between Al–M alloys activated with a liquid metal Ga–In eutectic and a chlorinating agent (CCl4) with the formation of catalytically active metal–aluminum chloride Al(M)/Cl complexes are established. Results from spectrokinetic measurements show the order of the reactivity of activated alloys with respect to excess CCl4 is Al–Cu ≈ Al–Ni > Al > Al–Co. The highest catalytic activity is displayed by nickel–aluminum chloride complexes whose selectivity toward ethylbenzene is 48%. Data from IR and UV-VIS spectroscopy show that the structure and composition of metal chloride complexes formed in situ in the aromatic reaction medium is determined by a combination of coupled ionic pairs ([{text{AlC}}{{{text{l}}}_{4}}]_{{{text{tetr}}}}^{ - }{text{/[NiC}}{{{text{l}}}_{{text{6}}}}]_{{{text{oct}}}}^{{4-}}) and (left[ {{text{AlC}}{{{text{l}}}_{{text{4}}}}} right]_{{{text{tetr}}}}^{ - }/left[ {{text{CuC}}{{{text{l}}}_{{text{2}}}}} right]_{{{text{lin}}}}^{ - }), which are stabilized by (C6H5)3C+ carbocation.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"14 4","pages":"363 - 368"},"PeriodicalIF":0.7,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4641603","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}
