| 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. |
