Subject Production of higher fatty acid esters
Published date Mar 12, 2008
Title Processes for producing higher fatty acid esters
Patent Application Number EP1897865 A1
Assignee Tokyo Inst Tech, Japan
Relevance A process of producing biodiesel oil at high efficiency from feed oil containing a free fatty acid.
Type of claims Publication
Overview This patent discloses processes of producing a higher fatty acid ester from starting materials such as soy bean oil, sunflower oil, palm oil, coconut oil, microalgae oil, wood oil and waste oil from a home or factory at a temperature of about 80-120 degree Celsius. The obtained higher fatty acid esters can be used as diesel fuel or the like. The processes comprises, A) producing a higher fatty acid ester by reacting a lower alcohol with a higher fatty acid in the presence of an amorphous carbon having a sulfonate group, B) producing a higher fatty acid ester by reacting a lower alcohol with higher fatty acid triglyceride in the presence of an amorphous carbon having a sulfonate group and C) producing a higher fatty acid ester by reacting the unreacted lower alcohol with the unreacted higher fatty acid triglyceride in the presence of an alkali hydroxide.
