MICROWAVE HEATING-BASED THERMOCHEMICAL HYDROGEN PRODUCTION SYSTEM, HYDROGEN PRODUCTION METHOD THEREFOR AND USE THEREOF

摘要

Provided are a microwave heating-based thermochemical hydrogen production system, a hydrogen production method therefor and use thereof. The hydrogen production system is as follows: the inlet of a preheater (3) is in communication with a carrier gas storage device (1), and a flow controller (2) is provided therebetween; the outlet of the preheater (3) is respectively in communication with the inlet of a steam generator (13) and one end of the second-three-way valve (5) via the first-three-way valve (4); the other two ends of the second-three-way valve (5) are respectively in communication with the outlet of the superheater (14) and the inlet of a reactor (7); the reactor (7) is provided in a microwave generation device (6); the outlet of the steam generator (13) is in communication with the inlet of the superheater (14) via a pipeline; the outlet of the reactor (7), a condenser (9), a drying device (10) and a collection device (12) are successively communicated; and a chromatograph (11) is provided on a communication pipeline between the drying device (10) and the collection device (12). Microwave pyrolysis of metal oxides has the characteristics of low energy consumption and fast temperature rise, so that the cost of experiments can be reduced, the cycle of repeated experiments is reduced, and the effective energy utilization rate is greatly improved.
