The hydro-processing of palm oil in a continuous mini fixed-bed reactor to produce bio-hydrogenated diesel (BHD) was investigated to improve the production biofuel. Rh/HZSM-5 was used as catalyst to facilitate cracking, hydrogenation, and isomerization reactions. The operating parameters included reaction temperature (400–500 °C), pressure (7–34 bar), weight hourly space velocity (10.0–43.7 h⁻¹), and hydrogen-to-oil molar ratio (36.6:1–220.9:1). The optimal conditions were at reaction temperature of 500 °C, pressure of 34 bar, 0.05 g of catalyst, WHSV of 43.7 h⁻¹, and hydrogen-to-oil molar ratio of 36.6:1. The yield and productivity of C₈-C₁₈ were 51.13% and 21.2 kgproduct/kgcath, respectively. The catalyst stability was demonstrated for 600 min. Fuel properties including density, viscosity, cloud point, pour point, acid value, and oxidation stability of the product collected at the optimal conditions were measured and compared with the US and European standards as well as the commercially available B-20 and B100-FAME in Thailand. The extremely short residence time (< 1 min) and the significant decrease in the use of hydrogen were observed along with the high-quality fuel when compared to the other processing techniques.

研究了在连续小型固定床反应器中对棕榈油进行加氢处理以生产生物加氢柴油 (BHD)，以提高生物燃料的产量。Rh/HZSM-5 用作催化剂以促进裂化、加氢和异构化反应。操作参数包括反应温度 (400–500 °C)、压力 (7–34 bar)、重时空速 (10.0–43.7 h ^-1 ) 和氢油摩尔比 (36.6:1–220.9: 1）。最佳条件为反应温度500°C、压力34 bar、催化剂0.05 g、WHSV 43.7 h ^-1和氢油摩尔比36.6:1。C ₈ -C ₁₈的收率和生产率分别为 51.13% 和 21.2 kgproduct/kgcath。催化剂稳定性被证明了 600 分钟。测量在最佳条件下收集的产品的燃料特性，包括密度、粘度、浊点、倾点、酸值和氧化稳定性，并与美国和欧洲标准以及市售的 B-20 和 B100-FAME 进行比较在泰国。与其他处理技术相比，观察到极短的停留时间（< 1 分钟）和氢气使用量的显着减少以及高质量燃料。
