  • Patent number: 4406822
    Abstract: A method of simultaneously producing or co-synthesizing a combination of zeolite X and zeolite A by separately preparing a sodium aluminate solution and a sodium silicate solution, adding the sodium aluminate solution to the sodium silicate solution activated with a relatively small amount of zeolite X seed or bulk product, mixing the solutions together under controlled conditions of temperature and time and heating the mixture to a desired temperature for sufficient time to form a product which is a combination of zeolite X and zeolite A of about 40 percent to 60 percent crystalline with the remainder being an amorphous functional binder.
    Type: Grant
    Filed: October 5, 1981

  • Patent number: 4188499
    Abstract: Primary alcohol containing impurities which have internal hydroxyl groups is purified to cause removal of such internal hydroxyl groups with reduced formation of ethers by treating the impure alcohol with an alumina catalyst which has been contacted with a hydroxide of a Group 1-A element. Preferably the alcohol treatment is concurrent with or followed by a hydrogenation treatment the purpose of which is to improve the iodine number of the treated alcohol.
