Catalytic hydrotreating of palm oil (refined palm olein type) to produce bio-hydrogenated diesel (BHD) was carried out in a continuous-flow fixed-bed reactor over NiMoS2/γ-Al2O3 catalyst. Effects of dominant hydrotreating parameters: temperature: 270-420°C; H2 pressure: 15-80 bar; LHSV: 0.25-5.0 h(-1); and H2/oil ratio: 250-2000 N(cm(3)/cm(3)) on the conversion, product yield, and a contribution of hydrodeoxygenation (HDO) and decarbonylation/decarboxylation (DCO/DCO2) were investigated to find the optimal hydrotreating conditions. All calculations including product yield and the contribution of HDO and DCO/DCO2 were extremely estimated based on mole balance corresponding to the fatty acid composition in feed to fully understand deoxygenation behaviors at different conditions. These analyses demonstrated that HDO, DCO, and DCO2 reactions competitively occurred at each condition, and had different optimal and limiting conditions. The differences in the hydrotreating reactions, liquid product compositions, and gas product composition were also discussed.
在连续流动固定床反应器中，使用 NiMoS2/γ-Al2O3 催化剂对棕榈油（精制棕榈油型）进行催化加氢处理，以生产生物加氢柴油（BHD）。考察了主要加氢处理参数（温度：270-420°C；H2 压力：15-80 巴；LHSV：0.25-5.0 h(-1)；H2/油比：250-2000 N(cm(3)/cm(3)))对转化率、产物产率以及加氢脱氧（HDO）和脱羰/脱羧（DCO/DCO2）贡献的影响，以确定最佳加氢处理条件。所有计算，包括产物产率以及 HDO 和 DCO/DCO2 的贡献，都是根据进料中脂肪酸组成的摩尔平衡进行极其精确的估算，以充分了解不同条件下的脱氧行为。这些分析表明，HDO、DCO 和 DCO2 反应在每种条件下都具有竞争性，并且具有不同的最佳和限制条件。还讨论了加氢反应、液体产物组成和气体产物组成的差异。
