Abstract
The purpose of this research work is to study the main aspects of catalytic cracking of heavy hydrocarbons on modified natural zeolite of the Shankanai deposit (Kazakhstan) with heteropoly acids. The leading methodological approach in this research work is a combination of a systematic analysis of the main aspects of performing catalytic cracking of heavy hydrocarbons with a practical study of the features of the functioning of the Shankanai deposit for obtaining and further practical use of modified natural zeolite and involving scientific experiments to determine the prospects for performing this kind of modifications, for the subsequent use of these zeolites in the processes of catalytic cracking of heavy hydrocarbons. The results obtained in this scientific study are clear evidence of the fact that more light oil fractions are obtained as a result of the catalytic cracking process using modified natural zeolites as a catalyst than as a result of thermal cracking under other similar initial conditions. The results obtained in this research work and the conclusions formulated on their basis are of significant practical importance from the standpoint of the prospects for the development of the Shankanai deposit and the use of the zeolite extracted from it after its modification in the processes of catalytic cracking of heavy hydrocarbons.
