Abstract The effect of operating parameters such as reaction mixture inlet pressure p 1 (101.3–1013.2 kPa), methanol to oil molar ratio M 1 (3–12), the concentration of catalyst C c (0.0–1.0 wt%), temperature T (25–50 °C) and the number of passes of the reaction mixture through the venturi type hydrodynamic cavitation reactor n (1–12) on alkali-catalyzed transesterification of sunflower oil with methanol assisted by hydrodynamic cavitation (ACTC) on the value of the degree of triglyceride conversion (DTC) was investigated. ACTC was performed by the venturi-type hydrodynamic cavitation reactor (VCR) of our construction. It was found that the values of DTC increase with the increase in p 1, M 1, C c, and n, and decrease with the increase in T. Cavitation yield (CY) values were calculated. The ACTC was proved to be the simplest, fastest, and most highly energy-efficient current technology for the production of biodiesel.

水动力空化-辅助碱催化葵花油与甲醇酯交换操作参数对甘油三酯转化率的影响

摘要 反应混合物入口压力 p 1 (101.3–1013.2 kPa)、甲醇油摩尔比 M 1 (3–12)、催化剂浓度 C c (0.0–1.0 wt%)、温度 T 等操作参数的影响(25–50 °C) 和反应混合物通过文丘里型流体动力空化反应器的次数 n (1-12) 在碱催化葵花油与甲醇的酯交换反应下通过流体动力空化 (ACTC) 的值研究了甘油三酯转化率（DTC）。ACTC由我们建造的文丘里型流体动力空化反应器（VCR）进行。发现 DTC 的值随着 p 1、M 1 的增加而增加，C c 和 n 随 T 的增加而减小。计算了空化产率 (CY) 值。ACTC 被证明是目前生产生物柴油最简单、最快和最节能的技术。
