| Abstract: | The acid leaching residue of coal gangue was calcined at 750℃for carbon removal,then it was mixed with sodium carbonate at a mass ratio of 1∶1.2 and calcined at 800℃for 1.5 h,the optimum conditions for the preparation of NaP molecular sieve were that:n(SiO2)/n(Al2O3)was 4.5,n(Na2O)/n(SiO2)was 1.5,n(H2O)/n(Na2O)was 35 and crystallized at 94℃for 9 h.The results show that the acid leaching residue of coal gangue can be activated completely by alkali melting,and the NaP molecular sieve with good crystallization can be obtained by hydrothermal crystallization. |
