在我们之前的研究中，固定化脂肪酶在超临界二氧化碳（SCCO2）和正己烷中的酶催化酯化反应的研究被扩展到管状固定床的连续操作。通过使用简单的塞流模型和适当的动力学方程，实现了反应容器运行的建模。与实验结果比较，结果令人满意。利用SCCO2进行了实验研究，获得了良好的选择性和产品回收率。©1994 John Wiley & Sons, Inc
The study of enzymatic esterification by an immobilized lipase in supercritical carbon dioxide (SCCO2) and in n‐hexane, described in our previous works, was extended to continuous operation in a tubular fixed bed. The modeling of the reaction vessel operation was achieved through the use of the simple plug flow model coupled with the appropriate kinetic equation. Comparison with experiments proved to be satisfactory. The study of the postreactional separation, an important feature when using SCCO2, was undertaken experimentally and good selectivities and product recovery were obtained. © 1994 John Wiley & Sons, Inc.
