Investigation of the Liquefaction Kinetics of the PolyE-IL-Catalyzed Catalytic Thermo Liquefaction Process for Organic Biodegradable Municipal Solid Waste

The catalytic thermo liquefaction (CTL) process with integration of the PolyE-IL catalyst has the specific advantages of high conversion, no char production, and nonstringent operating conditions. However, the study of the liquefaction kinetics is one of the most important parameters to elucidate the mechanism of the CTL process and a guide for process scale-up. The present manuscript demonstrates the elucidation of the liquefaction kinetics of a PolyE-IL-catalyzed CTL process for CTL of organic biodegradable waste. The CTL for different feedstocks showed >80% feed conversion at 120 °C in 120 min and under 10 bar inert gas pressure. Thus, both pressure and reflux reaction condition approaches for CTL were followed to investigate prevailing reactor parameters for liquefaction. However, the influences of reactor operating conditions with variable MSW slurry concentrations, temperatures, and times were inspected. The lower slurry concentration (
