<p>Provided is a method for manufacturing biodiesel fuel, which makes it possible to construct a distributed energy supply system that provides needed energy to locations that require the energy. The system is characterized by excellent storage stability, such that alcohol (subsidiary raw material) is not required, glycerin is not produced as a by-product, impurities such as dienes are unlikely to remain in the product, the amount of coke generated is small, the pour point is low, and blackening and abnormal odors rarely occur due to stability against air. The system is also characterized by excellent production efficiency and productivity which prevent running costs from increasing or productivity from decreasing due to secondary tasks such as treatment and reactivation of used catalysts. The system is further characterized by enabling a simplified manufacturing process and a simplified reactor without the need for pretreatment to remove free fatty acids from raw material fats. At 350 °C to 475 °C, a decomposition catalyst for fat decarboxylation and fats are brought into contact, an ester binding portion is cleaved in a decarboxylation reaction under the action of the decomposition catalyst for fat decarboxylation, and biodiesel fuel formed mainly from C8 to C24 hydrocarbons is obtained.</p> |
