This trend provides new methods and opportunities for the development of green synthetic chemistry. Taking the above into consideration, a critical review presented in this work emphasized the efficiency of catalyzing the synthesis of SEs with minimal hazardous by-products. These catalytic media have been employed with various impacts involving chemical, biological, and other catalytic materials. Chemical methods have been reported to show limitations in terms of preparation and bio-compatibility. To solve these shortcomings, therefore, other technologies have been adopted; ionic liquids (eutectic solvents), chemo-enzymatic systems and chemo-enzymatic systems on a catalytic surface. The use of chemo-enzymatic systems on catalytic surfaces has proved to be suitable in solving biocompatibility and stability problems and correspondingly increasing the yield of esters formed. Therefore, finding an improved catalytic surface, and the sustainable optimal reaction conditions for enzymes will be vital to improving sugar ester conversion. This study highlights the different catalytic advances employed in the esterification of SEs.","PeriodicalId":17783,"journal":{"name":"Kataliz v promyshlennosti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79126546","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 technologyis based on the use of catalysts supported on alumina with a hierarchical structure of meso- and macropores, which are highly active and stable under severe conditions of the process. Data obtained by physicochemical analysis of the chemical composition, textural and phase properties of fresh and spent catalysts for the three-step hydroprocessing of atmospheric residue and vacuum residue are presented. A material balance for each step of the processes and a comprehensive analysis of the properties of produced petrochemicals were used to propose variants of implementing and integrating the technology at Russian oil refineries in order to increase the profit from oil refining. The introduction of the hydroprocessing of atmospheric residue at oil refineries without secondary processes will improve the economic efficiency due to selling the atmospheric residue by 84–170 % depending on a chosen scheme of the process and a required set of products. It is reasonable to integrate the catalytic hydroprocessing of vacuum residue with the delayed coking, catalytic cracking and hydrocracking processes in order to increase the depth of refining to 95 % and extend the production of marketable oil refining products: gasoline, diesel fuel, marine fuel with the sulfur content below 0.5 %, and low-sulfur refinery coke for the electrode industry. The integration of the hydroprocessing of vacuum residue with the secondary processes will increase the economic efficiency from selling the vacuum residue by a factor of 2–2.5 in comparison with its production in delayed coking units.","PeriodicalId":17783,"journal":{"name":"Kataliz v promyshlennosti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80652538","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}

Due to implementation of this process on industrial level, the attention gradually shifts from scientific studies devoted to the synthesis and modification of zeolites and zeotypes with different structure to investigation of pilot and industrial plants and determination of the main economic and environmental characteristics of both the existing and the future plants. In 2019, the development of 26 production sites in China with the annual output of 14 million tons of ethylene and propylene was licensed and 14 plants with the total capacity of 7.67 million tons of ethylene and propylene were launched. The created plants provide a complete cycle of coal processing, which consists of coal gasification units yielding syngas, units for the synthesis of methanol and olefins, their refinement and production of polyethylene and polypropylene. The total output of ethylene and propylene at the launched plants was more than 21 million tons. The paper presents a review of publications on the development and modification of catalysts as well as the technological, economic and environmental aspects of olefins production from methanol, which appeared in foreign journals in the recent five years.","PeriodicalId":17783,"journal":{"name":"Kataliz v promyshlennosti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82188625","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 main component of natural gas is methane. Methane conversion processes are of great importance for society because natural gas, along with oil, supplies us with energy, fuel and chemical products. Direct and indirect methods of methane conversion are considered. Direct conversion of methane is often viewed as the holy grail of modern research, since methane molecules are very stable. The review considers the methods of obtaining such compounds as synthesis gas, methanol, ethylene, formaldehyde, benzene, etc. The greatest emphasis is placed on the direct processes of methane conversion, namely on the dehydroaromatization of methane. The catalysts and the conditions for their preparation are considered, the state of active centers is studied, and the mechanism of methane dehydroaromatization is proposed. The reasons for deactivation of the catalysts and methods of their regeneration are also described. This review will help to summarize the latest known achievements in the field of heterogeneous catalysis for natural gas processing.","PeriodicalId":17783,"journal":{"name":"Kataliz v promyshlennosti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74751162","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}
