Ni-Pt/ γ -Al 2 O 3 catalyst was prepared by step impregnation method with waste oil as raw material and Ni-Pt/ γ -Al 2 O 3 as carrier. Results showed that the waste oil used by catalytic hydrogenation of Ni-Pt the best preparation technology of Al 2 O? 3 catalyst for calcination temperature was 450 °C, the roasting time was 4 h, Ni/Pt ratio of 1:1, and the corresponding biological diesel oil production rate was 81.5%. A biodiesel yield of the regenerated catalyst was low and decreased with the increase of regeneration times. This process can improve the added value of gutter oil and provide experimental basis for the production of diesel distillate from waste oil.
