  • Hydrogenation of unrefined glyceride oils
    Patent number: 4169844
    Abstract: Unrefined or crude glyceride oil is hydrogenated in rapid fashion in the presence of nickel hydrogenation catalyst and of copper chromite adjunct catalyst. In a preferred embodiment of the invention, a nickel-only secondary hydrogenation stage follows for making a stearine in extremely rapid fashion.
    Type: Grant
    Filed: April 17, 1978
    Date of Patent: October 2, 1979
    Assignee: SCM Corporation
    Inventor: John M. Hasman
  • Hydrogenation of glyceride oils
    Patent number: 4158665
    Abstract: Glyceride oil contaminated with soap is hydrogenated in rapid fashion in the presence of nickel hydrogenation catalyst and of copper chromite adjunct catalyst, wherein the proportion of adjunct catalyst is adjusted broadly proportional to the soap concentration so that the hydrogenation proceeds substantially insensitively to said contaminant soap.
    Type: Grant
    Filed: November 10, 1977
    Date of Patent: June 19, 1979
    Assignee: SCM Corporation
    Inventor: John M. Hasman
  • Stearine production
    Patent number: 4158666
    Abstract: Glyceride oil is catalytically hydrogenated in rapid fashion to produce a stearine product.
    Type: Grant
    Filed: November 10, 1977
    Date of Patent: June 19, 1979
    Assignee: SCM Corporation
    Inventor: John M. Hasman
  • Trans acid restricted hard butters
    Patent number: 4134905
    Abstract: A non-fractionated, partially hydrogenated, non-lauric glyceride oil product suitable as a hard butter is made by hydrogenating the oil with copper-chromite catalyst to an Iodine Value of about 100-110 followed by hydrogenation with a conventional hydrogenation catalyst, suitably nickel, until hard butter characteristics of the fatty product are achieved.
    Type: Grant
    Filed: July 13, 1977

    Assignee: SCM Corporation
    Inventor: John M. Hasman
  • Hydrogenation of unsaturated fatty acid
    Patent number: 4133822
    Abstract: Unsaturated fatty acids refractory towards hydrogenation are rapidly and efficiently hydrogenated in the presence of nickel hydrogenation catalyst and of copper chromite adjunct catalyst with otherwise reasonably mild hydrogenation conditions.
