Abstract: The present disclosure relates to a system and a method for preparing carbon nanofiber and hydrogen through continuous microwave pyrolysis. The system includes four apparatus. The melting and feeding apparatus is to heat and melt feedstocks. The microwave pyrolysis apparatus is for catalytic pyrolysis and includes a feedstock inlet, a gas outlet and a carbon outlet. The gas purification and utilization apparatus is for hydrogen purification and residual gas separation, The power generation apparatus includes a generator and a small internal combustion engine utilizing residual gas as fuel, and the generated smoke is conveyed to the melting and feeding apparatus for feedstocks melting. According to the present disclosure, a poly-generation system for co-producing high-performance carbon materials and hydrogen through plastic wastes with greatly increased energy utilization rate is formed to solve the technical problems of low product yield and high energy consumption in traditional pyrolysis.
