【 摘 要 】

In this paper, the catalyst Ni-Pt/γ-Al2O3 was prepared by method of fractional steps and impregnation with gutter oil as raw material. Ni and Pt were selected as active components and γ-Al2O3 as carrier under 400°C setting conditions. The results showed that the reaction space velocity was 0.5 h-1, reaction pressure was 8.0 Mpa, hydrogen oil ratio was 1200:1, under the condition of above-mentioned facts, the pour point of biodiesel obtained from gutter oil hydrogenation was reduced by 9°C, cetane number was 57, yield was 74.03%. The yield of light component was significantly promoted, below 160°C fraction yield above 3.5%, the yield of diesel fractions could be reached 55.2%, the yield increased by 15%. This process greatly increased the additional value for the gutter oil and provided experimental basis for producing diesel fraction from gutter oil.
