Abstract
The present invention has an object to provide the following method for producing fatty acid alkyl esters and/or glycerin and the following catalyst used in the production method. According to the production method, a fat or oil is reacted with an alcohol to give a fatty acid alkyl ester and/or glycerin suitably used in a food or fuel application, etc., with high efficiency, and complicated steps such as a step of recovering a catalyst can be simplified or omitted. According to the catalyst, an active metal component is not eluted even if the catalyst is used repeatedly or for a long period of time, and further, such a catalyst can maintain an excellent catalyst activity for a long time even in the presence of water and exhibit a high activity to both of transesterification of a glyceride contained in the fat or oil and esterification of free fatty acid. In addition, the catalyst can exhibit a high catalyst activity even in the presence of an impurity such as a free fatty acid (FFA) contained in the fat or oil. The present invention is a method for producing fatty acid alkyl esters and/or glycerin including a step of bringing a fat or oil into contact with an alcohol in the presence of a catalyst, wherein the catalyst includes a manganese element and a trivalent metal element.
