We reported the dotted and dash performance curves illustrated in Fig. 5 for an anode-supported Ni5Al (SDC) / SDC / LSM (SDC) cell running on humidified methane and air mixtures in mixed-gas mode at 700°C with 02 C ratio of 1.5 and 1.67, respectively [6]. In the previous paper, we suggested that the decrease of cell performance for mixed-gas SOFC results from an increase in the anode polarization and is due to the low catalytic activity of the...

The volumes of product S atoms sampled by the ionization detector in the pulsed beam mode and in the gas mode are different. The determination of the intersection volume of the ionization laser beam and the CH3SCH3 beam, as well as that of the ionization laser beam and the CS molecules in the gas cell, is necessary for the calibration. The ionization dye laser beam profile is again assumed to conform with the Gaussian profile. The size of the CH3SCH3 beam is determined by the skimmer opening and the nozzle-skimmer distance. 

Resonance Raman spectroscopy has been shown to a particularly effective tool for differentiating between coordinated and uncoordinated phenoxyl radicals. Excitation into the 400 30 nm 7T 7T transition of metal-phenoxyl radical complexes leads to resonant enhancement of bands at l,500cm and 1,600cm. By analogy to experimental and calculated vibrational spectra for free phenoxyl radicals (e.g., these bands have been assigned as and j/ga modes,... 

Then Mendes et al. developed the pseudo-homogeneous 1-D model for the Pd-Ag finger-like shape membrane reactor and compared with the experimental results [13]. The simulation results are well agreed with the experimental results. Then they investigated this membrane reactor for parameter space such as temperature, pressure and sweep gas. Increasing reaction temperature increases the CO conversion up to 250 °C and further increase in reaction temperature decreases the CO conversion. However, H2 recovery increases with increasing temperature. Their simulation results suggest that it is possible to achieve 100% CO conversion both in sweep gas mode as well as vacuum mode. 

Some want to reduce costs of regeneration by using parallel burners in air and exhaust gas modes. Because of nonuniform packing of heat exchange materials, however, airflows and exhaust gas flows of regenerative burners are not identical, so each burner must have its own air/fuel ratio control and its own exhaust gas control system to provide near-maximum combustion efficiency.

The design of the two-zone steam pressurizer provides a self-sustaining water-gas mode in the primary circuit coolant under operating regimes of a NPP with a leak-tight primary circuit, without relief of the steam-gas medium from the pressurizer.
