To enhance the treatment capacity of solid waste and achieve diversified utilization of waste,a novel integrated system for producing methanol and oil was proposed based on the coupling of refuse-de-rived fuel(RDF)plasma gasification,hydrogen supplementation from water electrolysis,and tire pyroly-sis.The system centered on a plasma gasifier which drives a tire pyrolysis subsystem,achieving staged uti-lization of energy.Results show that the energy efficiency of the system is 58.24％and the exergy efficien-cy is 64.41％,with main energy loss in methanol synthesis and main exergy loss in plasma gasification.According to the results of the economic analysis,the total investment of the system is 35.665 6 million yuan.With a system life of 25 years and a dynamic payback period(DPP)of 3.15 years,the net present value(NPV)of the final system can reach 171.771 0 million yuan.
