Abstract

The invention discloses a carbon-based resource grading multi-element conversion system and method. A plasma hydrogen free radical catalysis module is used for receiving hydrogen discharged by a water electrolysis module and catalyzing the hydrogen to generate plasma hydrogen free radicals; the pyrolyzer is used for carrying out hydropyrolysis reaction on the solid carbon-based resource and plasma hydrogen free radicals to generate a gas product and a solid product; the plasma thermal cracking gasification module is used for converting a solid product discharged from the second outlet end into H2 / CO synthesis gas; the multi-phase product fine separation module is communicated with the first outlet end and is used for separating a gas product discharged from the first outlet end into a gas-phase product and a liquid-phase product; and the renewable energy power generation module is used for supplying power to the water electrolysis module, the plasma hydrogen free radical catalysis module and the plasma thermal cracking gasification module. The hydrogen free radicals are introduced into the pyrolytic reaction, the tar yield and quality are remarkably improved, and meanwhile the plasma is used for replacing a traditional gasification heat supply path to efficiently convert the semicoke.
