Description

technical field [0001] The invention relates to the field of pyrolysis treatment of biomass. More specifically, the present invention is a biomass spiral vibration electromagnetic induction pyrolysis reactor and a method for pyrolysis gasification, pyrolysis liquefaction and pyrolysis carbonization of biomass particles through the pyrolysis reactor. Background technique [0002] Biomass is a clean and renewable energy source. Biomass pyrolysis technology is an important way to utilize biomass. The so-called pyrolysis is to use heat energy to break up large molecular weight organic matter and transform it into low molecular weight substances with fewer carbon atoms. the process of. Biomass pyrolysis is a biomass thermal degradation process in which biomass produces liquid, gas, and solid products under complete anoxic conditions. [0003] According to experimental conditions such as temperature, heating rate, solid residence time (reaction time) and particle size, pyrolysis...
