Abstract
A rare earth- and phosphorus-containing molecular sieve of MFI structure rich in mesopores has a ratio of n(SiO)/n(AlO) of more than 15 and less than 70. The molecular sieve has a content of phosphorus of 1-15 wt %, calculated as POand based on the dry weight of the molecular sieve. The content of the supported metal in the molecular sieve is 1-10 wt % supported metal M1 and 0.1-5 wt % supported metal M2 based on the oxide of the supported metal and the dry weight of the molecular sieve. The supported metal M1 is one or two selected from lanthanum and cerium, and the supported metal M2 is one selected from iron, cobalt, nickel, copper, manganese, zinc, tin, bismuth and gallium; the volume of mesopores in the molecular sieve represents 40-70% by volume of the total pore volume of the molecular sieve by volume.
