Abstract�� Thermodynamic analysis was carried out for theoretical reaction of hydrogen produced from dimethyl ether(DME) partial oxidation reforming by using the element-potential method. The gas concentrations in the product gas were calculated under the constant-pressure and adiabatic condition as a function of air-to-DME ratio(0.5~4) and pressure(0.1~0.5MPa). The result proves that H2 concentration decreases with increasing of pressure. H2 concentration produces from DME partial oxidation reaction is the largest under atmosphere when air-to-DME ratio is about 3. The maximum is about 35%. By increasing air-to-DME ratio, H2 concentration increases firstly and then decreases, and CO concentration doesn-t changes obviously, and the concentration of CO2 and CH4 decreased respectively. Adiabatic temperature increases with increasing of air-to-DME ratio. At last, the experiment of hydrogen-rich gas produces from plasma reforming of DME is carried out on self-made equipments to verify the analysis, it proves that the concentration of H2,CO,CO2 and CH4 as a function of air-to-DME ratio analyzed by the element-potential method is almost in agreement with the experimental result.
