Influence of Feedstock Group Composition on the Octane Number and Composition of the Gasoline Fraction of Catalytically Cracked Vacuum Distillate

Thermodynamic parameters for the reactions of vacuum distillate catalytic cracking in a riser reactor have been calculated using the density functional theory. The list of the reactions has been compiled on the basis of laboratory studies on determining the group and structural-group composition of...

description	Thermodynamic parameters for the reactions of vacuum distillate catalytic cracking in a riser reactor have been calculated using the density functional theory. The list of the reactions has been compiled on the basis of laboratory studies on determining the group and structural-group composition of the vacuum distillate and the results of thermodynamic analysis. A kinetic model of the catalytic cracking process has been developed on the basis of a formalized scheme of the hydrocarbon conversion mechanism. By using the kinetic model derived, the effect of the group composition of four vacuum distillate samples on the octane number and the composition of the gasoline fraction of the catalytic cracking process has been assessed.
