Utilization method of catalytic cracking catalyst glue residues

The invention provides a utilization method of catalytic cracking catalyst glue residues, which comprises the following steps: (1) pulping the catalytic cracking catalyst glue residues until the solid content is 10-30 wt%, grinding, and then adding an alkaline solution for modification treatment; (2) aging the modified glue residue solution, an acidic aluminum source and a silicon source for 1-8 hours under the conditions that the pH value is 7-11 and the temperature is 10-90 DEG C; and (3) filtering, drying, and washing the dried solid to obtain the active silicon-aluminum matrix material. On the basis of the total weight of the silicon-aluminum matrix material, the prepared silicon-aluminum matrix material contains 0-3.0 wt% of Na2O, 20-50 wt% of Al2O3, 30-70 wt% of SiO2 and 1-15 wt% of RE2O3, the specific surface area of the silicon-aluminum matrix material is 200-500 m < 2 >/g, the pore volume is 0.5-1.0 mL/g, and the average pore size is 10-40 nm. 本申请提供一种催化裂化催化剂胶渣的利用方法，其包括以下步骤：(1)将催化裂化催化剂胶渣打浆，固含量为10～30重量
