Jatropha oil is a prospective non-edible resource for green diesel manufacturing. In this work, diesel-range hydrocarbons (mostly C₁₅–C₁₈n-paraffins) were produced from the hydrotreatment of jatropha oil over traditional CoMo/Al₂O₃ and NiMo/Al₂O₃ catalysts in a fixed-bed reactor. The reaction variables were varied as follows: temperature, 563–653 K; pressure, 1.5–3 MPa; H₂/oil ratio, 200–800 (v/v); and weight hourly space velocity, 1–4 h^–1. Oil conversion was maximized (Co–Mo, 97%; Ni–Mo, 88.6%) at T = 653 K and P = 3 MPa. The hydrocarbon yield at these conditions was 62.6% (Co–Mo) and 63% (Ni–Mo). These findings were juxtaposed with our latest results on the hydrotreatment of the non-edible karanja oil. From the first-order plots of conversion of triglycerides in jatropha oil, rate constants and energy of activation were found. To improve the cold flow properties of the hydrotreated jatropha oil without isomerization, it was blended with usual diesel in varying proportions. As the concentration of usual diesel in such mixtures increased, the viscosity, cetane number, and pour point decreased. Employing tailored blends of hydrotreated vegetable oil and petroleum diesel thus appeared preferential. Finally, the performance of Co–Mo and Ni–Mo catalysts prepared by wet impregnation was tested, but the activity of the commercial catalysts was superior.

使用Co-Mo和Ni-Mo催化剂生产加氢麻风树油并将其与石油柴油共混

麻疯树油是用于绿色柴油制造的潜在非食用资源。在这项工作中，在固定床反应器中，通过在传统的CoMo / Al ₂ O ₃和NiMo / Al ₂ O ₃催化剂上对麻风树油进行加氢处理，生产了柴油级碳氢化合物（大部分为C ₁₅ –C ₁₈ n-链烷烃）。反应变量的变化如下：温度563-653 K；温度563-653K。压力1.5–3 MPa；H ₂ /油比，200–800（v / v）；和重量时空速度，1–4 h ^–1。在T = 653 K和P时，油的转化率最大化（Co-Mo，97％； Ni-Mo，88.6％）= 3兆帕。在这些条件下，碳氢化合物的收率为62.6％（Co-Mo）和63％（Ni-Mo）。这些发现与我们对不可食用的魔芋油进行加氢处理的最新结果并列。从麻风树油中甘油三酸酯转化的一级曲线图中，可以找到速率常数和活化能。为了在不异构化的情况下改善加氢处理的麻风树油的冷流性能，将其与常规柴油以不同比例混合。随着此类混合物中常规柴油浓度的增加，粘度，十六烷值和倾点降低。因此，采用加氢处理的植物油和石油柴油的量身定制的混合物似乎是首选。最后，测试了通过湿法浸渍制备的Co-Mo和Ni-Mo催化剂的性能，但商用催化剂的活性更高。
