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.
