Hydrotreating of vegetable oils offers a green alternative to oil‐derived fuels and raw hydrocarbon materials, usually obtained from oil. In contrast to sulfided catalysts, which contaminate the product with sulfur, carbide‐based catalysts are able to produce clean hydrocarbons. A NiMo carbide‐based catalyst, supported on nanometric γ‐alumina was prepared, characterized by X‐ray crystallography, Nitrogen physisorption, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, and Raman spectroscopy. The oxidation temperatures and acidity were also determined. Tests were performed in a batch‐type reactor for the hydrotreatment of soybean oil at 360, 380, and 400°C and 4.5 MPa. Liquid samples were analyzed by gas chromatography with a mass spectra detector. The reaction rate was calculated showing that reactant concentration did not influence deoxygenation rates, nor did the catalyst revealed a significant change in the activity. The product composition was extensively characterized, proving that reaction temperature greatly influences the concentration of aromatic, unsaturated and saturated hydrocarbons, as well as chain size distributions.

反应参数对大豆油脱氧对碳氢化合物可持续生产的影响

植物油的加氢处理为通常来自石油的石油衍生燃料和原始烃原料提供了绿色替代品。与硫化催化剂污染了产品的硫化催化剂不同，碳化物基催化剂能够生产出清洁的碳氢化合物。制备了负载在纳米γ-氧化铝上的NiMo碳化物基催化剂，其特征在于X射线晶体学，氮物理吸附，扫描电子显微镜，能量色散X射线光谱和拉曼光谱。还确定了氧化温度和酸度。在批处理型反应器中进行了对大豆油进行360加氢处理的测试，380、400°C和4.5 MPa。用气相色谱仪用质谱检测器分析液体样品。计算出反应速率，表明反应物浓度不影响脱氧速率，催化剂也没有显示出活性的显着变化。对产物的组成进行了广泛的表征，证明反应温度极大地影响了芳烃，不饱和烃和饱和烃的浓度以及链的大小分布。
