摘要

对在搅拌釜中进行的半连续脂肪酸甲酯化过程进行了分析

提出了3级混合室模型.并考虑了反应温度、压力、催化剂、反应釜容积及冷凝器持料量等因素对过程的影响.采用四阶变步长龙格-库塔法对模型求解.对不同反应条件下脂肪酸甲酯化实验过程进行的模拟表明

实验数据与模型计算结果吻合较好.该模型可应用于反应温度378～513K、反应压力2MPa以下、催化或非催化的混合脂肪酸半连续酯化过程的模拟.

Abstract

On the basis of the study of semi-batch esterification of higher fatty acid by methanol in agitated reactor

the authors proposed a three pools mixing model taking into consideration the effects of temperature

pressure

catalyst

reactor volume and condenser hold-up. The present model is solved by using a Runge-Kutta method with varying steps. It is shown that the agreement between calculated values and experimental data is satisfactory. The model is applicable in simulating the semi-batch esterification of mixed higher fatty acid in the temperature range between 378K and 513K with or without catalyst and under the pressure up to 2 MPa.
