Figure 6a shows the effect of F02 on the C2 selectivity and yield. The C2 yield is up to 53%. Figure 6b refers to the same experiments and shows the corresponding elBfect of CH4 conversion on the selectivity and yield of ethylene and ethane. The ethylene yield is up to 50% (65% ethylene selectivity at 76% methane conversion). To the best of our knowledge this is the maximum ethylene yield obtained for the OCM reaction under continuous-flow steady-state conditions. [Pg.394]

Part I appeared in Advan. Carbohyd. Chem., 23, 233-280 (1968). All numbers for Figures, Formulas, References, and Sections in Part II continue the sequence established in Part I. References common to Parts I and II are listed for the convenience of the reader. [Pg.139]

Experimental Results. The solution redox potentials (18) and gas-phase photoelectron spectroscopy of metallocenes (79) have received much attention in the literature. We have recently used charge-transfer equilibria in the FTICR-MS to determine the values of aG for several metallocenium ions (Figure 1). Reference compounds are not widely available for alP values < 6.8 V, so the absolute values for many metallocenes of lower IP have not yet been determined. However, alP values in the desired range are known (77), and we are continuing these studies. [Pg.76]

The edges that come from these badges can be annotated with parameters (passed to and from sub-steps). This is also shown in the figure under reference. In case, when there is no sub-step/exception handler, respectively, then the badges previously described (control flow or exception handler) are omitted (refer to blank boxes at the bottom side). It is possible for an exception to have a null handler, in which case the continuation badge alone determines how execution proceeds. [Pg.971]

For higher ambient temperatures, current capacity should be suitably reduced to maintain the same end temperature during continuous operation. Refer to Tables 28.3(a) and (b), recommending the derating factors for a higher ambient temperature or a lower temperature rise for the same end temperature of 85° or 90°C respectively. For intermediate ambient temperatures, see Figure 28.10. [Pg.869]

The primary reference method used for measuring carbon monoxide in the United States is based on nondispersive infrared (NDIR) photometry (1, 2). The principle involved is the preferential absorption of infrared radiation by carbon monoxide. Figure 14-1 is a schematic representation of an NDIR analyzer. The analyzer has a hot filament source of infrared radiation, a chopper, a sample cell, reference cell, and a detector. The reference cell is filled with a non-infrared-absorbing gas, and the sample cell is continuously flushed with ambient air containing an unknown amount of CO. The detector cell is divided into two compartments by a flexible membrane, with each compartment filled with CO. Movement of the membrane causes a change in electrical capacitance in a control circuit whose signal is processed and fed to a recorder. [Pg.196]

When the eore s flux is eompletely emptied prior to the next cyele, it is referred to as the discontinuous-mode of operation. This is seen in the induetor eurrent and voltage waveforms in Figure 3-4. When the eore does not eompletely empty itself, a residual amount of energy remains in the eore. This is ealled the continuous mode of operation and ean be seen in Figure 3-5. The majority of boost-mode eonverters operate in the diseontinuous mode sinee there are some intrinsie instability problems when operating in the eontinuous mode. [Pg.25]

F = Function of the molecular volume of the solute. Correlations for this parameter are given in Figure 7 as a function of the parameter (j), which is an empirical constant that depends on the solvent characteristics. As points of reference for water, (j) = 1.0 for methanol, (j) = 0.82 and for benzene, (j) = 0.70. The two-film theory is convenient for describing gas-liquid mass transfer where the pollutant solute is considered to be continuously diffusing through the gas and liquid films. [Pg.257]
