Abstract
A process for producing diesel fuel oil from fat and oil comprises producing fatty acid methyl ester for diesel fuel in accordance with transesterification of the fat and oil with methanol, wherein the process further comprises a step of converting glycerol formed as a by-product into methanol, and the obtained methanol is used as a material for the transesterification. In the step of converting glycerol formed as a by-product into methanol, water in an equimolar amount or more to the amount of glycerol is added to glycerol, the obtained mixture is gasified under a pressure of 2 MPa or greater at a temperature of 700° C. or higher to convert the mixture into a gas comprising carbon monoxide and hydrogen, and carbon monoxide and hydrogen are then converted into methanol in accordance with a methanol synthesis process.
