Abstract
A molecular sieve complex contains an oxide of aluminum, an oxide of an alkaline earth metal and a rare earth-modified molecular sieve. The rare earth-modified molecular sieve is a molecular sieve doped by a rare earth element. The percentage of the pore volume occupied by pores of 3 nm or less to the total pore volume in the molecular sieve complex is greater than or equal to 63.5%. The content of the rare earth element and the contents of the oxide of aluminum, the oxide of the alkaline earth metal and the molecular sieve satisfy a certain relationship. The composite material contains a molecular sieve complex and an auxiliary agent loaded on the molecular sieve complex, and the composite material may be applied to flue gas adsorption and desulfurization.
