This is because when the heating temperature is getting higher and higher, organic compounds occurs a chemical reaction to produce the chemically stable and relatively low density material, for example CH4, CO2, water and so on, making the relative density and the amount of hydrocarbon decreased, methanation coefficient increased, the critical pressure increased, the critical temperature decreased.
Therefore, it can be directly used as raw Chemical materials and fuel.
After microwave heating treatment, the oil phase can be directly used as raw chemical materials and fuel, and more susceptible to be reuse
