Development of new catalytic processes for processing petroleum feedstock

Currently such factors as the use of heavier feedstocks, permanent strengthening of requirements to oil and gas product quality, introduction of technical regulations for oil products, which, in turn, necessitate the development of new technologies and catalysts, have a great influence on the global oil-refining and petrochemical industry development. Recently, a special attention is given to the development of new catalysts and processes for producing middle distillate fuels suitable for cold and arctic climatic conditions. Catalytic hydrodewaxing and isodewaxing processes are the most efficient in this field. Research into controlling a functional structure of catalysts and creation of catalytic systems based on zirconium dioxide modified by tungstate anions are of outstanding interest. The trend of the use of heavier petroleum feedstocks and the need to improve the oil conversion level demand will be based on destruction of high-molecular-weight compound structures with producing light and middle cuts. So, the most important processes for heavy oil residue conversion are those enabling to control transformations of resinous-asphaltenic materials by using nanoscale catalytic systems. One of the examples of the industrial implementation of technologies using suspended catalysts is the hydroconversion process implemented currently at AO TANECO (lisencer: TIPS RAS; general designer: OAO VNIPIneft).
