  • Patent number: 11028337
    Abstract: A structure for adsorbing contaminants from cooking oil comprises: an outer shell comprised of a filter material; and an adsorbing mixture comprising rice hull ash blended with a reinforcing binder, wherein the adsorbing mixture is in the form of particles having a particle size from about 0.30 millimeters (300 microns) to about 1.40 millimeters (1400 microns), with an average particle size of about 0.60 millimeters (600 microns) to about 0.70 millimeters (700 microns). The adsorbing mixture is enclosed by the outer shell, such that, in use, cooking oil with the contaminants passes through the outer shell, contacts the adsorbing mixture within the outer shell, and then again passes through the outer shell with substantially fewer contaminants.

  • Patent number: 10961466
    Abstract: A Process for the purification of renewable oils. The process may also be applied to petroleum oils such as used motor oil and the like. The process involves centrifuging the renewable oil in a centrifugal device producing a minimum of 7000 RCF, then contacting the oil with a mixture containing water, a straight chain hydro-treated ester compound, and a phosphate derivative at a minimum temperature of 100° C. for 10 minutes, then raising temperature to approximately between 120° C. and 130° C. to complete reaction. The mixture is then again centrifuged in a centrifugal device producing a minimum of 7000 RCF.

  • Patent number: 8642824
    Abstract: Various methods are provided for metathesizing a feedstock. In one aspect, a method includes providing a feedstock comprising a natural oil, chemically treating the feedstock under conditions sufficient to diminish catalyst poisons in the feedstock, and, following the treating, combining a metathesis catalyst with the feedstock under conditions sufficient to metathesize the feedstock.

  • Publication number: 20110033595
    Abstract: The present invention relates to a concentration- and purification method for compositions containing phytanic acid and/or derivatives thereof besides other fatty acids and/or their derivatives, preferably besides polyunsaturated fatty acids and/or their derivatives, such as esters or salts. With the fractionation process the phytanic acid (derivative) can become concentrated and the fatty acid mixture, preferably PUFA-mixture, can be purified from this particular component.

  • Patent number: 6610870
    Abstract: Processed linseed oil essentially consisting of linolenic, linolic and oleic acids, mainly in the form of triglycerides, its content of free tocoferol being less than about 100 ppm; and a process for the manufacture of linseed oil comprising the following steps: a) heating crude linseed oil to an increased temperature lower than the boiling point of water, b) adding a heated inorganic acid to the oil and mixing the oil, c) separation of precipitated materials, d) adding a heated aqueous solution of alkali to the oil and mixing the oil, e) discharge of the soap formed, and f) rinsing the oil with hot water until a clear rinsing water is obtained.

  • Patent number: 5138075
    Abstract: The present invention provides an extractive separation method in which a solute contained in a medium can be efficiently extracted and separated with a lower consumption of energy under the remarkably gentle operating conditions. This method consists in that a medium containing a solute consisting of organic substances is brought into contact with a solvent consisting of organic substances or inorganic substances, which have the critical temperature of 5.degree. to 152.degree. C.

  • Patent number: 5110509
    Abstract: Described is a process for the recovery of monoglycerides and diglycerides from a mixture containing monoglycerides, diglycerides and triglycerides by extraction with a supercritical extractant which comprises specific cosolvents. After the separation of the monoglycerides as bottom product in the separation column, the extract consisting of diglycerides and triglycerides is separated into diglycerides and triglycerides by fractionated pressure decrease and change of temperature in two consecutive regeneration columns. A portion of the product obtained in the first regeneration column is fed as reflux to the head of the separation column, and a portion of the product, obtained in the second regeneration column, is fed as reflux to the head of the first regeneration column for an improved separation.
