Transesterification catalyst and method for producing biodiesel fuel using the catalyst

摘要

The present invention relates to a catalyst for producing biodiesel fuel that can produce biodiesel fuel with high selectivity, high yield, and low cost even in the presence of moisture and free fatty acids, and biodiesel fuel using this catalyst Oil and fats by using titanium-containing mesoporous silica having Ti and Si as skeleton constituent elements and having a pore diameter of 5 nm or more as a transesterification catalyst. The transesterification of alcohol with alcohol makes it possible to produce biodiesel fuel with high selectivity and high yield.
