The application discloses a high-strength, large-pore-volume
phosphorus-containing binder, characterized in that the binder comprises a glue, a curing agent and a modifier; the glue comprises a
phosphorus-containing compound and an aluminum-containing compound; the curing agent comprises a gamma-aluminum
oxide precursor, an acid and an alkylammonium salt, and the modifier is a
metal chelate; wherein the colloidal
solubility index of the gamma-aluminum
oxide precursor is less than or equal to 50%; and the modifier is reacted with the glue in a high-shear dispersion emulsifier. The
phosphorus-containing binder provided by the application, in combination with a conventional method, can obtain a catalytic
cracking catalyst which, on the basis of high
molecular sieve content and
large pore volume, still has
high wear resistance.
