PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing petroleum-alternative fuel having high purity while dispensing with a cleaning step. SOLUTION: The method for producing petroleum-alternative fuel comprises: an ester interchange step of subjecting oils and fats to an ester interchange reaction in the coexistence of alcohol and an alkali catalyst to produce a mixture of the petroleum-alternative fuel with glycerol being a by-product; and a distillation step of distilling the produced mixture under reduced pressure of≤5 mmHg at 150-300°C liquid temperature in order to separate the petroleum-alternative fuel from the glycerol while agitating the mixture together with a solvent used at the ester interchange step to distill/extract the petroleum-alternative fuel.
