MESOPOROUS ALUMINOSILICATES AS PROMISING CARRIERS OF CATALYSTS FOR PETROCHEMICAL PROCESSES

Nowadays there is a number of research papers and a certain interest in some mesoporous materials and the study of their properties. Mesoporous materials have every chance to become components of industrial heterogeneous catalysts. Catalysts based on mesoporous aluminosilicates are widely used in the petrochemical industry for hydrogenation, reforming, hydroisomerization, hydrocracking, hydrodearomatization, etc. In this article mesoporous aluminosilicates (MAS) were synthesized by copolycondensation of tetraethylortosilicate and secondary aluminum butoxide. Hexadecylamine was used as a template. The physico-chemical characteristics of a synthesized structured mesoporous aluminosilicate and a bifunctional catalyst based on it were studied by nitrogen adsorption/desorption, X-ray diffraction, SEM and TPDA. It was found that the obtained samples have an ordered mesoporous structure and possess the necessary strength and concentration of acid centers for use as acid components of bifunctional catalysts of various petrochemical processes.
