The catalyst activity was tested using an autoclave type reactor and three different oil to alcohol ratios (1 : 3, 1 : 5 and 1 : 7) at four different temperatures (50–80°C) for 4 h. Two types of alcohol (i.e. methanol (CH3OH) and ethanol (C2H5OH) were used to understand the efficiency of using alcohol in the process. The study indicates that reaction using high ratio of alcohol (1 : 7) generally produced high yield of the biodiesel compared to other ratios. The yield of the biodiesel also increased with increasing temperature over all the reaction systems. The carbon modified with sulphuric acid catalyst showed the highest yield of ~ 90%, which was obtained at 80°C using a 1 : 7 ratio of WCO : alcohol. It was also observed that reaction with methanol produced better yields compared to ethanol reactions where significant differences were observed across both temperature and ratio. The catalysts were characterized using Fourier transform infrared spectroscopy, X-ray powder diffraction, surface area and pore volume analyses. The catalyst is of interest because it is green, non-toxic and synthesized using cassava peel waste.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"15 1","pages":"99 - 107"},"PeriodicalIF":0.7,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4909299","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 development of efficient catalysts solves the problem of replacing fossil fuels with ultra-clean alternative fuels and reduces their negative impact on the environment. An analysis of results from scientific and technological research, including ones obtained recently by the authors, shows current lines in developing the technology of high-performance catalysts for the Fischer–Tropsch synthesis of hydrocarbons using classical and integrated GTL technology, including the creation of new types of polyfunctional systems. The review mainly describes the catalytic characteristics of supported cobalt catalysts synthesized via impregnation and polyfunctional hybrid catalysts obtained on their basis for the selective synthesis of fuel fraction hydrocarbons. Problems of controlling selectivity, productivity, and changes in the activity and physicochemical properties of catalysts during long-term operation are considered.","PeriodicalId":507,"journal":{"name":"Catalysis in Industry","volume":"15 1","pages":"6 - 20"},"PeriodicalIF":0.7,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4909302","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}

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}
