Modeling and Numerical Simulation of Hydrogen Production from Dimethyl Ether Steam Reforming

Abstract

In order to study the steam reforming process of dimethyl ether, a kind of reformer reactor with thermal jacket, heat pipe and catalytic reaction bed was designed. The effects of reaction gas temperature, molar ratio of water to ether and the structure parameters of the reactor on the conversion of dimethyl ether, the yield of hydrogen, the hydrogen concentration at the outlet of the reactor and the concentration of CO2 were investigated experimentally. The mathematics and power of the reactor were established Learn model The COMSOL software was used to simulate it. The simulation results showed the temperature distribution, mass distribution, DME conversion and hydrogen production in DME steam reforming process. These simulation results will provide useful data for the design and operation of small scale catalytic reforming bed reactors.
