摘要
Abstract
Experimental study showed when n (SiO2) /n (Al2O3)≈3.3, Na2O/SiO2 was 1.2～1.5, H2O/Na2O was 40～70, the gel temperature was 60 -70 ℃, time continued 2h, reaction temperature was 90 -95 ℃, the crystallization time continued 4 -6 h, the fly ash of circulating fluidized bed boiler could synthesize the molecular sieve of higher crystallinity. It had better characteristic peak of P zeolite by the characterization of XRD, good stability by TGA. The relative degree of crystallization was 53%.关键词
