907“…It is of great significance to develop energy-efficient routines that can synthesize zeolites Na-A and Na-X from low-cost raw materials. Coal fly ash (CFA) is the major residue from the combustion of coal and biomass containing more than 85% SiO(2) and Al(2)O(3), which can readily replace the conventionally used sodium silicate and aluminate for zeolite synthesis. …”
