The article discusses the urgent problem of industrial methods for increasing the octane number that improve the quality of gasoline produced. These methods include the processes of catalytic reforming and compounding of gasoline. Reforming from "to reform" (English) — to remodel, to improve. Reformate, depending on the production technology and composition of the raw material, may contain up to 70 % of the mass. aromatic hydrocarbons. Attention to this problem is due to the tightening of environmental requirements for the quality of motor fuel that must comply with modern standards. An effective solution to this problem is to model refining processes with programming. In this article, we apply methods of correlation and regression analysis. Using these methods, you can establish the relationship between two or more variables, thus finding the most effective solution to both technological and economic issues.
