[0002] Pyrolysis carbonization refers to the technology of converting organic matter into carbon residue liquid and gas products by heating under oxygen-free or low-oxygen environment. It is widely used in energy production, carbon material preparation, and waste treatment. Its advantages are: it can not only realize the resource utilization of waste, but also reduce environmental pollution and greenhouse gas emissions. With the growing global demand for renewable energy and environmental protection technology, pyrolysis carbonization technology has received widespread attention as an effective method to convert organic waste into high-value-added products; especially for the current treatment of biomass and solid waste, it provides a more reasonable solution.
