Abstract
This is a research on the hydrodesulphurization process of hydrogenate from the coal of Shubarkolsky deposit (Republic of Kazakhstan) in the presence of pyrite and natural zeolite. The rate constants for hydrodesulphurization process of the liquid products and Gibbs energy were calculated by the method of equilibrium kinetic analysis, which was necessary for improving the technological parameters for the hydrotreatment of liquid hydrogenation products. It is shown that the optimal time of the hydrodesulphurization process is 15-25 minutes. The sulfur content in the fraction up to 2000С is 0.043 %, and in a fraction of 200-3000С - 0.065 %, which indicates a high degree of hydrotreatment of the hydrogenate in the presence of the above mentioned catalyst.
