Investigation of the parameters of the process of obtaining low-sulfur coke from heavy oil residues in the presence of a recycling agent

The current state of the oil refining industry is characterized by obtaining high-quality products that meet environmental requirements. An important issue is the deep processing of oil, as well as the use of oil waste as raw materials. In this regard, there is an interest in putting oil raw materials into operation through destructive processes: catalytic cracking, thermal cracking, visbreaking, coking, and processing of most of the oil waste. The article shows the possibility of producing coke with a low sulfur content from heavy oil waste from a domestic oil field. The physical and chemical properties of the extracted distillates are determined by chromatographic analysis and determined that the group-hydrocarbon composition corresponds to the composition of fractions obtained from primary atmospheric distillation. The process of obtaining of low-sulfur coke used as a conductor and oxidizer of electric current and raw materials in the production of structural material in the presence of a recycling agent from heavy oil waste from the Kumkol field was studied
