The regeneration process typically involves the following steps:
Loading the spent catalyst into a high-pressure reactor. Introducing the supercritical fluid, often supercritical CO2, into the reactor. Maintaining the reactor at the desired temperature and pressure to keep the fluid in its supercritical state. The supercritical fluid dissolves and removes contaminants from the catalyst. Recovering the cleaned catalyst and separating the contaminants from the supercritical fluid.
