  • Glycerol derived material
    Patent number: 10590055
    Abstract: A method of producing a solid glycerol derived material includes the steps of combining glycerol with a metal oxide, the glycerol having a water content of between about 5 and 50%, and the rate of combination of the glycerol and the metal oxide and the amount of the metal oxide being selected so that at least part of the water present in the glycerol reacts with the metal oxide in an exothermic reaction and at least part is driven off by heat produced in the exothermic reaction to produce the solid glycerol derived material.
    Type: Grant
    Filed: July 22, 2014
    Date of Patent: March 17, 2020
    Assignee: BIO-ENERGY INGREDIENTS LIMITED
    Inventors: Richard Alwyn Houseman, Abraham Christo Venter

  • METHOD OF REDUCING THE RATE OF DEGRADATION OF A BIOLOGICAL MATERIAL
    Publication number: 20120009280
    Abstract: A method of producing an animal feed product from a wet biological material, having a physical form selected from solutions, suspensions, emulsions, gums, mousses, sludges, slurries, and particulate materials, includes the step of combining the biological material with a base comprising a metal oxide in an amount which is sufficient to heat the biological material to a temperature of above 50° C. by reaction of water in the biological material with the metal oxide to produce the animal feed product. The product has a physical form which is easier to handle than that of the wet biological material and is selected from particulate materials and, granular materials. The base is preferably calcium oxide.
