Direct synthesis and characterization of high-SiO2-content mordenites

A direct synthesis of high-SiO2-content mordenite without addition of organic compounds was studied. The effects of starting raw materials, substrate composition, aging time, and reaction temperature on the crystallization rates were investigated. Morphology, N2 sorption capacity, surface area, thermal stability of crystals, and hexane-cracking property of the silica-rich mordenite are also reported.
