Disclosed is a method for producing series of phase change wax products, comprising: refining a Fischer-Tropsch synthesis wax raw material via a hydrogenation reaction to obtain a refined Fischer-Tropsch wax; and subjecting the refined Fischer-Tropsch wax to reduced pressure distillation to separate continuous fractions with a distillation range of 5 C.-30 C. by continuously increasing the operation temperature so as to obtain series of phase change wax products, wherein the pressure for the reduced pressure distillation is 0-1000 pa, the operation temperature at the top of the column is 120 C.-260 C., and the phase change enthalpy value of the series of phase change wax products is 170 J/g. According to the method, phase change wax products of various grades with melting points from 5 C. to 80 C. can be separated and produced from the refined Fischer-Tropsch wax. The products have concentrated carbon numbers and relatively high enthalpy values. The process products have relatively high flexibility, can be customized on demand, and have low production cost, and the industrial production of the products can be realized.
