|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.|
