A packed-bed catalytic configuration reactor using pumice granules loaded with lithium (Li/Pumice) as a heterogeneous catalyst was developed for biodiesel production in continuous. For this purpose, Jatropha curcas oil was used as an alternative feedstock to edible oils and diethyl ether was used as a cosolvent to eliminate the limitations of mass transfer between the phases. In this work, the response surface methodology was applied to optimize the fatty acid methyl esters (FAME) yield in biodiesel production. The flow rate (0.7–1.4 mL min⁻¹), the methanol/oil molar ratio (6:1–20:1) and the cosolvent/methanol molar ratio (0.5:1–1.5:1) were the independent variables studied. The effects of these factors over the FAME yield using Li/Pumice as catalyst were evaluated according to a Box-Behnken design. The optimum conditions for the maximum FAME yield (100%) were 1.4 mL min⁻¹, 20.0 methanol/oil molar ratio and 0.57:1 cosolvent/methanol molar ratio.

开发了一种填充床催化配置反应器，使用负载锂的浮石颗粒（Li/Pumice）作为非均相催化剂，用于连续生产生物柴油。为此，麻疯树油用作食用油的替代原料，乙醚用作助溶剂以消除相间传质的限制。在这项工作中，应用响应面法来优化生物柴油生产中的脂肪酸甲酯 (FAME) 产量。流速（0.7–1.4 mL min ^-1)、甲醇/油摩尔比 (6:1–20:1) 和助溶剂/甲醇摩尔比 (0.5:1–1.5:1) 是研究的自变量。根据 Box-Behnken 设计评估这些因素对使用 Li/Pumice 作为催化剂的 FAME 产率的影响。获得最大 FAME 产率 (100%) 的最佳条件是 1.4 mL min ^-1、20.0 的甲醇/油摩尔比和 0.57:1 的助溶剂/甲醇摩尔比。
