Application of new porous binder material in fluid catalytic cracking reaction

A novel porous binder was obtained by acid-treated kaolin. This new binder owned abundant meso-macro pore and good hydrothermal stability. The prepared catalyst using new binder had a character of low attrition index and large pore volume. The catalysts were tested in a fixed-fluidized bed unit. Compared with comparison sample, the conversion of new catalyst was increased by 0.73%, heavy oil yield decreased by 1.11%, the total liquid and light oil yield increased by 0.95% and 0.74%, respectively. The perfect pore structure and good hydrothermal stability of new binder were the possible reason of obtaining prominent performance.
