Document Type and Number:
WIPO Patent Application WO/2023/236388
Kind Code:
A1
Abstract:
A method for strengthening the separation of a mixed component by means of a supercritical fluid combined medium. The supercritical fluid combined medium comprises a supercritical fluid and a cosolvent. A method for separating organic matter in the mixed component comprises the following steps: placing the mixed component and the cosolvent in a reaction container, suspending the mixed component above the liquid level line of the cosolvent, introducing the supercritical fluid into the reaction container, and subjecting same to supercritical fluid separation, wherein during the process of supercritical fluid separation, the separation temperature is periodically changed within the supercritical temperature range of the supercritical fluid combined medium. By means of the characteristic that the characteristic parameters of the supercritical fluid combined medium change along with the temperature, a relatively high separation yield can be obtained under the conditions of low energy consumption, the separation treatment time can be shortened, and the separation efficiency of the mixed component in a supercritical fluid environment is effectively improved.
