  • Forming and crystallization process for molecular sieve manufacture
    Patent number: 4058586
    Abstract: A method of preparing zeolitic aluminosilicates particularly those zeolitic aluminosilicates that are characterized by pores in the 4 and 10A sizes that are designated Zeolites A and X by the Linde Division of Union Carbide Corporation in which compacts of the Zeolites A and X, metakaolin, clay mixture undergo crystallization at a temperature of 200.degree. to 700.degree. F. The crystallization is carried out in a calciner or other type of drying equipment. Normally the formed particles furnish all of the liquid needed for crystallization. If desired, however, additional steam may be added during the crystallization process.
