-
Influencing factors for the synthesis of LSX molecular sieve, such as LSX seed, nK/nNa and crystallization conditions were investigated in detail. The products were characterized by XRD, SEM, XRF, FTIR and N2 adsorption-desorption. The results revealed that the addition of LSX seed could accelerate the rates of crystal nucleation and growth, and inhibit the formation of A type and sodalite zeolites. Furthermore, too high or too low value of nK/nNa in the synthesis gel would obtain A type and sodalite impurities. Crystallization at high temperature directly would lead the conversion of metastable LSX zeolite into more thermodynamically stable zeolite phase. The Si-Al ratio, the surface area and N2 adsorption capacity of the end product decreased with the extending of aging time and the increasing of crystallization temperature.
