This work presents biodiesel production from soybean oil and bioethanol by multiple-stage Ultra-Shear reactor (USR). The experiments were carried out in the following conditions: reaction time from 6 to 12 min; catalyst concentration from 0.5% to 1.5% by weight of soybean oil; ethanol: soybean oil molar ratio from 6:1 to 10:1. The experimental design was used to investigate the influence of process variables on the conversion in biodiesel. The best ethyl ester conversion obtained was 99.26 wt.%, with ethanol:soybean oil molar ratio of 6:1, catalyst concentration of 1.35% and with 12 min of reaction time.
本文采用多级超声反应器（USR）从大豆油和生物乙醇生产生物柴油。实验在以下条件下进行：反应时间 6-12 分钟；催化剂浓度为大豆油重量的 0.5%-1.5%；乙醇：大豆油摩尔比为 6:1 至 10:1。实验设计用于研究工艺变量对生物柴油转化率的影响。在乙醇：大豆油摩尔比为 6:1、催化剂浓度为 1.35%、反应时间为 12 分钟的条件下，得到的最佳乙酯转化率为 99.26wt.%。
