Patent number: 7652156Abstract: A method allowing, from natural fat or oils, vegetable or animal, or from other glyceride mixtures, to obtain in a quasi-quantitative way fatty acid ethyl esters that can be used as gas oil substitutes, comprises the succession of stages as follows: a stage (a) wherein the oil, the fat or the glyceride mixture is transesterified by ethanol using a soluble catalyst or a catalyst that becomes soluble during the reaction, a stage (b) wherein the glycerin formed is decanted and removed, without requiring an excess ethanol evaporation operation, a stage (c) wherein a second transesterification reaction is carried out so as to obtain a product whose ester content is at least 97% by mass, a stage (d) wherein controlled neutralization of the catalyst is carried out, a stage (e) wherein the excess ethanol is removed by distillation, a stage (f) wherein the ester undergoes purification by means of water wash sequences, and a stage (g) wherein the ester mixture is dried under reduced pressure.Type: GrantFiled: September 20, 2006Date of Patent: January 26, 2010Assignee: Institut Francais du PetroleInventors: GĂ©rard Hillion, Bruno Delfort

Patent number: 6399802Abstract: Methods for acidification of soapstock and recovery of acidulated fatty acids are disclosed. Further methods of conversion of the acidulated fatty acids to esters are also disclosed. Further methods of crystallizing the acidulated fatty acids from the extraction solvent at low temperatures and fractionating the acidulated fatty acids from the extraction solvent using urea are also disclosed. The novel method of adding both a monohydric alcohol to the soapstock to lower viscosity and a strong acid to hydrolyse the soaps prevents the formation of emulsions of soaps and oils. The preferred embodiment uses a soapstock such as soybean soapstock, sulphuric acid and isopropanol. The novel process allows the quantitative recovery of fatty acids and glyceride from the soapstock by removal of the alcohol by evaporation. Alternatively the fatty acids and glyceride may be converted to esters of monohydric alcohols.Type: GrantFiled: March 21, 2001Date of Patent: June 4, 2002Assignee: KRU Feed Energy CompanyInventor: Martin J. T. Reaney

Patent number: 5696278Abstract: The present invention relates to a process for the preparation of degummed glyceride oils, which comprises applying an acid degumming treatment to a crude glyceride oil which has not substantially been exposed to enzymatic activity. Preferably such crude glyceride oil has been obtained by heating and pressing glyceride oil containing vegetable material, optionally preceded by a cold pressing step, where the heating comprises an exposure of the vegetable material to a temperature of 30.degree.-80.degree. C. for 0.1-20 minutes, preferably for 0.1-15 minutes, more preferably 0.1-5 minutes, and then to a temperature of 80.degree.-140.degree. C., preferably 90.degree.-110.degree. C. for 1-60 minutes, preferably 15-20 minutes. Residual phosphorus levels of <7 ppm and even <2 ppm can be easily and consistently attained.Type: GrantFiled: December 13, 1995Date of Patent: December 9, 1997Assignee: Unilever Patent Holdings B.V.Inventor: Jacobus Cornelis Segers

Patent number: 5565590Abstract: This invention relates to a process for recycling waste material selected from amino-carboxylic acid oligomers or polymers and amido-carboxylic acid oligomers or polymers into amido-carboxylic acids. A mixture containing water, an oligomeric or polymeric waste material, and a carboxylic acid is heated. The mixture is cooled to obtain a two phase system containing an aqueous phase and an organic phase which are separated. Carboxylic acids, unreacted starting materials, and the monomeric amido-carboxylic acid product are distilled from the organic phase. The remaining solid residue composed of high boiling oligomeric amino-carboxylic acids is recycled into Step (A).Type: GrantFiled: November 7, 1994Date of Patent: October 15, 1996Assignee: Eastman Chemical CompanyInventors: George C.

Patent number: 5424466Abstract: A description is given of an improved process for the production of esters from fatty substances having a natural origin (animal and vegetable oils) and low molecular weight alcohols, in which the soaps and oily compounds entrained in the alkaline phases are recycled by treating them, following acidification and separation, with a fraction of the glycerol phase produced, in the presence of an alkaline catalyst and for forming preferably a triglyceride or a partly substituted glyceride.This process makes it possible to quantitatively obtain methyl, ethyl, propyl or butyl esters usable as a substitute for gas oil.Type: GrantFiled: September 24, 1993Date of Patent: June 13, 1995Assignee: Institut Francais du PetroleInventors: Robert Stern, Gerard Hillion, Jean-Jacques Rouxel

Patent number: 5156879Abstract: The present invention is directed to a method for treatment of soapstock obtained by alkali refining of fats to provide a fluid, uniform, pumpable animal feed product. In the method, a raw soapstock is provided. The soapstock is pretreated by adding a strong, soluble base to the soapstock. Propionic acid is then added to the pretreated soapstock and the pH is adjusted to provide an acidified soapstock. With soapstocks having low gum levels, a fluid, uniform, pumpable product is provided without further treatment. At higher gum levels, the pretreated soapstock and/or the acidified soapstock is heated to a predetermined temperature to provide the fluid, uniform, pumpable product.Type: GrantFiled: July 25, 1991Date of Patent: October 20, 1992Assignee: Cargill, IncorporatedInventor: Jeffrey C.
