Abstract. Calculation method to determine the group composition of the heavy fraction of vacuum distillate with high content of saturated hydrocarbons, obtained by vacuum distillation of the residue from the West Siberian oil with subsequent hydrotreating, are given in this research. The method is built on the basis of calculation the physico-chemical characteristics and the group composition of vacuum distillate according to the fractional composition and density considering with high content of saturated hydrocarbons in the fraction. Calculation method allows to determine the content of paraffinic, naphthenic, aromatic hydrocarbons and the resins in vacuum distillate with high accuracy and can be used in refineries for rapid determination of the group composition of vacuum distillate.

The testing results of the cracking zeolite catalysts using the mathematical model of catalytic cracking are given in this research. The mathematical model is based on the formalized scheme of hydrocarbon conversions according to the results of laboratory research using gas chromatography-mass spectrometry and thermodynamic analysis of the catalytic cracking reactions using quantum chemistry methods. The effect of the catalyst composition on the distribution of the catalytic cracking products, the content of propane-propylene and butane-butylene fraction in wet gas, group composition and octane number of gasoline, the content of coke on the catalyst are determined using the mathematical model of catalytic cracking
