Hydrogen Production from Dimethyl Ether and the Catalysts Development
1.Introduction It is expected that fuel cell is one of the methods for restraint of the global green effect. Steam reforming of fossil fuels is actively researched and developed as hydrogen supply methods for the fuel cells. Dimethyl ether (DME) dose not contain the poisonous substances, and it burns without particulate matters (PM), without sulfur oxide (Sox), and with less nitrogen oxide (Nox). DME is expected as a clean fuel of the 21 st century1. DME has also recently become a potential fuel for hydrogen production to be used in fuel cells. DME is able to take the place of light oil and LPG, and its physical properties are similar to those of LPG. There is possibility that DME infrastructures will be settled more rapidly than those of hydrogen, because LPG infrastructures existing are able to be used for DME. I have been studying on steam reforming of DME for the hydrogen production. The new type catalysts prepared by a sol-gel method have been developed 2-5. These catalysts produce hydrogen more effectively at lower reaction temperature than mixed catalysts with DME hydrolysis catalysts and methanol steam reforming catalysts. Cu-Zn (29-1wt％)/Al2O3 is the most effective catalyst for hydrogen production in my recent study. In this paper, aiming at practical use of the catalysts, catalyst life time tests (durability tests) were carried out. In order to reduce the pressure loss and in order to make the catalysts inexpensive, fixation of the catalysts on commercial alumina was examined.
