The method of producing a biodiesel fuel using a transesterification catalyst and the catalyst

The present invention is highly selective biodiesel even in the presence of moisture and free fatty acids, high yield, a catalyst for biodiesel production that can be manufactured at low cost, and biodiesel fuel using this catalyst a is an object of the present invention to provide a method of manufacturing, as an ester exchange catalyst has a Ti and Si as a skeleton constituent element, the use of the titanium-containing mesoporous silica is the pore diameter is 5nm or more oils and fats and an alcohol of the ester interchange, makes it possible to produce a biodiesel fuel high selectivity, in high yields.
