Abstract

The present application relates to the technical field of device temperature control, and more particularly to a 12-hydroxystearic acid production reaction temperature control method based on artificial intelligence, which comprises the following steps: calculating a reaction heat release index based on the instantaneous molar flow of hydrogen feed at the current time to represent the theoretical heat generated by chemical reaction per unit time; constructing a viscosity correction factor for representing the degree of heat transfer capacity attenuation caused by the change of material viscosity based on the output power of the stirring motor and the fluid mechanics characteristics at the current time; combining the reaction heat release index and the viscosity correction factor at the current time to perform energy compensation and nonlinear correction on the in-situ measured temperature in the reactor at the current time to obtain a target predicted temperature; and controlling the 12-hydroxystearic acid production reaction temperature based on the target predicted temperature at the current time, which can effectively improve the accuracy of 12-hydroxystearic acid production reaction temperature control.
