Development of a Nuclear Hydrogen Production System by Dimethyl Ether (DME) Steam Reforming and Related Technology

Production of hydrogen by unmixed steam reforming of methane

Hydrogen production by sorption-enhanced steam reforming of glycerol.

Catalytic steam reforming of glycerol for H(2) production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700 degrees C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in situ CO(2) removal. The product gases were measured...

Sustainable Hydrogen Production by Catalytic Bio-Ethanol Steam Reforming

Chemical Recuperation of Low-Grade Exhaust Heat by Steam Reforming of Dimethyl Ether

For the new process of effective utilization of energy, chemical recuperation of low-grade exhaust heat by steam reforming of dimethyl ether (DME) was proposed. Steam reforming of DME is an endothermic reaction as; DME + 3H2O + 122[kJ/mol] → 6H2 + 2CO2. If this reaction could be proceed by exhaust heat below 573 [K], those exhaust heat which is wasted to ambient would be recuperated as the fuel...

Hydrogen production by steam reforming of dimethyle ether over Cu/ZnO/Al2O3 and H-ZSM-5 catalysts: An experimental and modeling study

Hydrogen was produced by steam reforming of dimethyl ether (DME) using a physical mixture of commercial HZSM-5 zeolite (for DME hydrolyzing) and Cu/ZnO/Al2O3 (for methanol steam reforming) as a catalyst in a fixed bed reactor. The experiments were performed at atmospheric pressure and in a temperature range from 270 to 310 °C. The effects of feed temperature and gas hourly space velocity (GHSV)...
