This paper summarizes the progress of C₅/C₆ alkanes steam cracking and catalytic cracking, but the key problem of the above method is the high yield of low-value C₁–C₃ alkanes. When C₅/C₆ olefin is used as the feedstock of catalytic cracking, the ethylene and propylene yields are high, while the C₁–C₃ alkanes yield is low. It is of scientific value to dehydrogenate the C₅/C₆ alkanes into the corresponding olefins, and effectively convert the olefins into ethylene and propylene. This paper reviews recent progress of direct catalytic dehydrogenation and oxidative dehydrogenation of C₅/C₆ alkanes, and points out that the key is to develop C₅/C₆ alkanes dehydrogenation catalyst for selective preparation of corresponding mono-olefins. The main issues about how to develop highly selective C₅/C₆ alkanes dehydrogenation catalysts are proposed.</p></div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":"26 4","pages":"245 - 260"},"PeriodicalIF":3.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10563-022-09367-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4814186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XRF, XRD, HRTEM, PL and UV–Vis DRS techniques were employed to investigate physicochemical, structural and optical properties of the synthesized nanopowders with the average particle size of 9 nm. Nanopowders xFe/nano-Al₂O₃ as model catalysts were tested in isobutane dehydrogenation reaction. The results obtained were compared with similar data for the xFe/γ_Pb-Al₂O₃ systems synthesized by the conventional sol–gel method. According to XRD and UV–Vis DRS data, in the series of xFe/nano-Al₂O₃ samples a great part of Fe³⁺ ions is in the disordered environment of subsurface layers of Al₂O₃ nanocrystallites, predominantly in the tetrahedral coordination. In distinction to samples of the xFe/γ_Pb-Al₂O₃ series, in the case of nanostructured xFe/nano-Al₂O₃ powders the formation of Fe₂O₃ phase does not occur at any concentrations of iron or conditions of testing. The analysis of the PL spectra of xFe/nano-Al₂O₃ powders also showed the presence of surface sites of Fe³⁺ ions, which were not detected for xFe/γ_Pb-Al₂O₃. Catalytic testing of the xFe/nano-Al₂O₃ series samples in isobutane dehydrogenation revealed the formation of the iron active sites that ensure catalytic activity of the samples. Differences in the catalytic properties of FeO_x/Al₂O₃ samples obtained by the sol–gel method and laser vaporization are related to different states of Fe³⁺ ions. Thus, the xFe/nano-Al₂O₃ nanopowders, in contrast to xFe/γ_Pb-Al₂O₃, contain a large amount of active Fe³⁺ sites. These sites, being involved in the dehydrogenation reaction, are present predominantly on the surface of the nanopowders.\u0000</p></div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":"26 4","pages":"322 - 335"},"PeriodicalIF":3.0,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4964422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
