| titleOfInvention | In situ crystallized cracking catalyst and preparation method thereof |
| abstract | Belonging to the field of solid waste treatment and application, the invention relates to an in situ crystallized cracking catalyst and a preparation method thereof. The method is characterized by synthesizing a fluid catalytic cracking catalyst in situ the raw material of fluid catalytic cracking waste catalyst fine powder. The preparation method comprises the steps of: removing the heavy metal components of vanadium, nickel, etc. from a fluid catalytic cracking waste catalyst through pickling, calcinating a mixture of the pickled waste catalyst and alkali under high temperature for activation, subjecting the activated waste catalyst, water glass, kaolin, an auxiliary agent, a dispersant or/and a binder, etc. to spray drying so as to form a microballoon A, then subjecting the microballoon A, water glass, water and a guiding agent, etc. to a crystallization reaction, thus obtaining a crystallized microballoon with a NaY zeolite content of 20-70% and a zeolite-silica-alumina ratio of 4.0-6.0. Then, after the steps of calcination, filtration, washing and the exchange of NH4+ and/or Re3+ and/or phosphor, a cracking catalyst product can be obtained. The catalyst of the invention has the characteristics of high heavy metal tolerance, high cracking activity, good stability of activity, simple preparation process, low cost, etc. |
