  • Impregnation of coke with an organic compound to produce a molecular sieve
    Patent number: 3962129
    Abstract: Porous coke is impregnated with an organic compound which remains in the pores thereby causing a reduction in the effective size of the same. This results in molecular sieve coke capable of separating different gases, particularly oxygen and nitrogen, and capable of adsorbing smaller gas molecules more rapidly than larger gas molecules. The organic compound has a boiling point of at least 200.degree.C as measured at atmospheric pressure and of no more than 450.degree.C as measured in vacuum.
