| 20100228042 | METHOD AND APPARATUS FOR PREPARING FATTY ACID ALKYL ESTER USING FATTY ACID - A method and an apparatus for preparing fatty acid alkyl ester for bio-diesels are disclosed, wherein fatty acid, specifically fatty acid distillate reacts with alcohol, without a catalyst. The method does not require the purification process of the catalyst and glycerin, and has the superior conversion ratio of fatty acid. The method for preparing fatty acid alkyl ester for bio-diesel fuels comprises the step of esterifying fatty acid raw material with alcohol, under a temperature of 200 to 35O0 C and a pressure of atmospheric pressure to 10 bar. The apparatus for preparing fatty acid alkyl ester for bio-diesel fuels, comprises: the first reactor for esterifying fatty acid raw material with alcohol under a temperature of 2000 C to 35O0 C and a pressure of atmospheric pressure to 10 bar and for converting 80 to 90% of total fatty acid into fatty acid alkyl ester; and the second reactor for converting remaining fatty acid unconverted at the first reactor into fatty | 09-09-2010 |
| 20110065942 | PROCESS FOR PREPARING ESTERS OF ALCOHOLS AND GLYCERIN FROM TRIGLYCERIDES AND ALCOHOLS USING A HETEROGENEOUS CATALYST IN THE PRESENCE OF A CONTROLLED QUANTITY OF WATER - A process for preparing a composition of alcoholic esters of straight chain monocarboxylic acids containing 6 to 26 carbon atoms and glycerin, starting from a vegetable or animal oil, neutral or acidic, virgin or recycled with mono-alcohols containing 1 to 18 atoms, in the presence of a zinc aluminate catalyst and in the presence of a controlled quantity of water, can directly produce, in one or more steps, an ester which can be used as a propellant or fuel along with glycerin having improved purity containing a reduced quantity of ethers by using a partially dried catalyst. | 03-17-2011 |

| 20150353864 | Process for the Production of Bio-Naphtha from Complex Mixtures of Natural Occurring Fats & Oils - A process for making a bio-diesel and a bio-naphtha from a complex mixture of natural occurring fats & oils may include subjecting the complex mixture to a refining treatment for removing non-triglyceride and non-fatty acid components, thereby obtaining refined oils. The complex mixture or refined oils may be subjected hydrolysis for obtaining glycerol and free fatty acids. The free fatty acids may be subjected to fractionation for obtaining: a liquid part (phase L); and a solid part (phase S). The phase L may be transformed into alkyl-esters as bio-diesel by an esterification. The phase S may be transformed into linear paraffins as the bio-naphtha by: hydrodeoxygenation or decarboxylation of the free fatty acids; or obtaining fatty acids soaps from the phase S and decarboxylation of the fatty acids soaps. | 12-10-2015 |
