Synthesis of Mesopore Y Zeolite

Y zeolite has been widely used in the petroleum processes, especially in the fluid catalytic cracking and hydrocracking catalysts. The catalytic performance of the Y zeolite depends strongly on the modification; it is well recognized that the mesopore Y zeolite with diameters between 0.8-60 nm is good for cracking large molecules. To obtain this kind of Y zeolite, chemical modification in hydrothermal treatment is one of effective methods.
