Thermodynamic analysis of mixed and dry reforming of methane for solar thermal applications

Thermodynamic analysis of the reforming of methane with carbon dioxide alone （＂dry reforming＂） and with carbon dioxide and steam together （＂mixed reforming＂） is performed as part of a project which investigates the suitability of these endothermic reactions for the storage of solar thermal energy. The Gibbs free energy minimization method was employed to identify thermodynamically optimal operating conditions for dry reforming as well as mixed reforming with a desired H2/CO molar ratio of 2. The non-stoichiometric equilibrium model was developed using FactSage software to conduct the thermodynamic calculations for carbon formation, H2/CO ratio, CH4 conversion and H2 yield as a function of reaction temperature, pressure and reactant molar ratios. Thermodynamic calculations demonstrate that in the mixed reforming process, optimal operating conditions in a carbon-free zone are under H2O/CH4 /CO2 =1.0/1.0/0.5, p = 1 to 10 bar and T = 800 to 850℃ for the production of syngas with a H2 /CO molar ratio of 2. Under the optimal conditions, the maximum H2 yield of 88.0% is achieved at 1 bar and 850℃ with a maximum CH4 conversion of 99.3%. In the dry reforming process, a carbon formation regime is always present at a CO2/CH4 molar ratio of 1 for T = 700 1000℃ and p = 1-30 bar, whereas a carbon-free regime can be obtained at a CO2/CH4 molar ratio greater than 1.5 and T≥800℃.

Operation Conditions Optimization of Hydrogen Production by Propane Autothermal Reforming for PEMFC Application

Autothermal reforming (ATR) is one of the leading methods for hydrogen production from hydrocar- bons. Liquefied petroleum gas, with propane as the main component, is a promising fuel for on-board hydrogen producing systems in fuel cell vehicles and for domestic fuel cell power generation devices.

One operation point was chosen with the following process parameters: feed temperature for the ATR reactor is 425℃, steam to carbon ratio S/C is 2.08, air stoichiometry is 0.256. Thermal efficiency for the integrated system is calculated to be as high as 84.0 % with 38.27 % H2 and 3.2μl·L-1 CO in the product gas.

PEMFC Application in a Gliding Arc Plasam-Catalysis Reforming System using Biogas

In this study, bio-waste gas is converted to sustainable hydrogen energy in good quality and low pollution. In addition, generated highly concentrated hydrogen is applied to fuel cell (PEMFC) to resolve environmental and energy crisis issue via gliding arc plasma system. Parameters that can affect the reforming performance of bio-gas in gliding arc plasma system were studied. Especially, the optimal operating condition in water gas shift reactor and preferential oxidation reactor for CO removal was proposed. For the parametric re-searches, change in steam feed amount and temperature change in catalyst bed in water gas shift reactor were studied. For the preferential oxidation reactor, air input flow rate change and temperature variation in catalyst bed were evaluated. The optimal operating conditions for gliding arc plasma reforming system are proposed as 6:4 of biogas component ratio (i.e., CHR4R:CO), 3 of steam/carbon ratio, 16 L/min of total gas flow rate, and 2.4 kW of input electric power. Where, the concentration of biogas that passed each reactor shows 57.5% of HR2R, 7 ppm of CO, 9.2% of COR2R, and 3.4% of CHR4R. Therefore, less than 10 ppm of CO is achieved, and this system can be applicable for PEMFC.

Preparation of High Surface Area Mesoporous Ni_2xCe_1-xO₂(x = 0, 0.05, 0.13, 0.2) and Its Applications in Methane Steam Reforming

The present study proposes a novel reverse precipitation procedure, which is different from the conventional precipitation method, for the synthesis of ultra high surface area mesoporous CeO2 at various conditions. Mesoporous Ni2xCe1-xO2 (x = 0.05, 0.13, 0.2) is also synthesized for use in the methane steam reforming reactions. The physicochemical properties of the catalysts and catalytic activity tests for the steam reforming of methane are also investigated. In the present study, the preparation of high surface area mesoporous CeO2 is proposed, which successfully enables control over the surface area. The results showed that the highest surface area of mesoporous ceria reached 695 m2/g. Tests on long-term catalytic activities indicated that Ni0.4Ce0.8O2 exhibited a much greater stability and activity for the steam reforming of methane than the others. Further, the present work also found that the amount of mobile oxygen increased simultaneously as the nickel content in the proposed catalysts due to the synergistic effects of structural nickel species to the oxygen vacant sites at the vicinity of the surface. Using the proposed new method, mesoporous ceria can be utilized more extensively in many ways, including as a three-way catalyst, as an electrolyte of solid oxide fuel cells, in reforming reaction, and in some other practical applications.
