Abstract (English):
The article presents the results of a study of the catalytic activity of zeolite-containing siliceous rock from the Tatarsko-Shatrashansky deposit in the Republic of Tatarstan. X-ray phase analysis of the rock sample revealed the content of the crystalline phase of zeolite and amorphous aluminosilicates, which have acidic properties and can exhibit catalytic activity. A comparative comparison of the characteristics of zeolite-containing siliceous rock with an industrial fluid catalytic cracking (FCC) catalyst has been carried out. It was found that the specific surface area of the zeolite-containing rock is lower than that of the FCC industrial catalyst, but the average pore diameter is larger. The composition of alkane cracking products with zeolite-containing siliceous rock is characterized by extremely low gas output. In the course of experimental studies, the optimal temperature at which the maximum conversion of n-alkanes is observed was determined and the composition of their cracking products was analyzed. Analysis of the results showed that the studied zeolite-containing rock has a certain catalytic activity. However, it is inferior in its characteristics to the FCC industrial catalyst. The composition of the reaction products revealed a predominance of unsaturated hydrocarbons, which may indicate the occurrence of cracking and dehydrogenation reactions. The results obtained can be useful for further research in the development of new catalysts and optimization of hydrocarbon processing processes.
