| Abstract:With the increasing energy problems in the world, hydrogen energy, as a kind of efficient and clean energy, is particularly important for the research of fuel cell.In this paper, the process of hydrogen production by steam reforming of dimethyl ether is studied. A reforming reactor with heat insulation jacket, tile heating channel and catalytic reaction bed is designed.The effects of temperature of reaction gas, molar ratio of water vapor to dimethyl ether and reactor structure parameters on the conversion rate of dimethyl ether, the yield of H2, and the content of H2 and C02 at the reactor outlet were studied experimentally.The mathematical model and power model of the reactor were established, and the COMSOL software was used to simulate the reactor.The simulation results show the mass distribution of each component, the conversion rate of dimethyl ether and the hydrogen productionrate under different temperature and water ether molar ratio.These simulation results provide useful data to promote the design and operation of micro catalytic reforming bed reactor. |
