1. A modified Y-type molecular sieve, having a rare earth oxide content of about 4% to about 12% by weight, a phosphorus content of about 0% to about 10% by weight on the basis of P2O5, a sodium oxide content of no more than about 1.0% by weight, a total pore volume of about 0.36 mL/g to about 0.48 mL/g, a percentage of a pore volume of secondary pores having a pore size of 2-100 nm to the total pore volume of the modified Y-type molecular sieve of about 20% to about 40%, a lattice constant of about 2.440 nm to about 2.455 nm, a percentage of the non-framework aluminum content to the total aluminum content of the modified Y-type molecular sieve of no more than about 10%, a lattice collapse temperature of not lower than about 1060° C., and a ratio of Brønsted acid to Lewis acid in a total acid content of the modified Y-type molecular sieve of no less than about 3.5, as determined by pyridine adsorption infrared spectroscopy at 200° C., and
wherein the modified Y-type molecular sieve has a framework structure of zeolite Y.
