ABSTRACT:
Synthetic Na,K-ferrierite, a molecular sieve zeolite capable of intracrystalline adsorption of molecules, is prepared by hydrothermal synthesis in the water, soda, potash, alumina, silica system. Crystallization is best achieved in the temperature range of 230.degree.-310.degree. C and autoclaving times of 2-96 hours with the use of co-precipitated silica-alumina gels and Na and K carbonates and bicarbonates.
