Effect of CO

The physical properties of ionic liquids can often be considerably improved through the judicious addition of co-solvents [55-58]. Flowever, surprisingly, this approach has been relatively underutilized. Flussey and co-workers investigated the effect of co-solvents on the physical properties of [EMIM]C1/A1C13 ionic liquids [55, 56]. They found significant increases in ionic conductivity upon the addition of a variety of co-solvents. Figure 3.6-5 displays representative data from this work. The magnitude of the conductivity increase depends both on the type and amount of the co-solvent [55, 56]. [Pg.117]

The results of a systematic study of the effect of Co in an alloy series corresponding to LaNi43 Co Mn Al,., are shown in Fig. 13 and summarized in Table 6 and graphically in Fig. 14. The correlation between expansion and corrosion is rather weak e.g., even though the H content is unchanged. It is thus likely that corrosion inhibition by Co is also due to a surface effect as with Ce. In this connection Kanda et al. [48] found evidence that Co sup-... [Pg.222]

It is concluded that a fully satisfactory system for calculating simultaneous reactions of CO and COo with H2 and H20 will require a schedule of the effect of CO on C02 methanation as a function of temperature. This effect will probably be different with different particle sizes. From a commercial standpoint, the particle size range may be too small to require much difference in the treatment of the data, but in the laboratory very small particle size may lower the CO methanation rate. A simple kinetics system such as that derived from Equation 3 may be satisfactory for all the reactions. It is unlikely that reliable data will be collected soon for the shift reaction (since it is of a somewhat secondary nature and difficult to study by itself), and therefore a more complicated treatment is not justified. [Pg.78]

For CO methanation, one of the simple literature kinetic systems (2, 3) should be as reliable or better than the one used in this study. With C02 methanation, it is less certain that a simple system is indicated. It is probably of more urgency to elucidate the quantiative effect of CO on C02 methanation than to find a complex kinetic expression for the C02-H2 reaction itself. [Pg.78]

The effect of °Co y-ray irradiation on the mechanical properties, surface morphology, and fractography of blends of plasticized PVC and thermoplastic copolyester elastomer, Hytrel (E.I. Du Pont de Nemours Company, Inc., Wilmington, Delaware), have been studied by Thomas et al. [445]. Radiation has two major effects on the blend cross-linking of the Hytrel phase and degradation of PVC phase. Both effects are found more prominent at higher radiation dose. [Pg.904]

Adsorbed CO and NO were used as probes to Investigate the effects of Co concentration and sulfide on the nature and numbers of exposed metal sites on reduced catalysts containing 1 to 6 wt% Co and 8 wt%. Mo on three alumina supports. Exposure of Mo Ions decreased with Increased Co concentration. Exposure of Co Ions typically reached a maximum at 2-4% Co. Sulfide decreased exposure of all metal Ion sites and Increased exposure of reduced metals. Effects of preadsorbed pyridine and 2,6-lutldlne, known poisons, on the exposure of metal sites, plus other evidence. [Pg.422]

The degradation of trichloroethene by methylotrophic bacteria involves the epoxide as intermediate (Little et al. 1988). Further transformation of this may produce CO that can toxify the bacterium, both by competition for reductant and by enzyme inhibition (Henry and Grbic-Galic 1991). The inhibitory effect of CO may, however, be effectively overcome by adding a reductant such as formate. [Pg.224]

The effect of co-extracted matrix components on the analyte response in the final determination step should be assessed. Normally, this is done by comparing the response of standards in solvent with matrix-matched standards, i.e., standards prepared in the extract of a control sample without residues. Because matrix effects tend to be inconsistent, the guidelines propose the general use of matrix-matched calibration unless it is demonstrated to be unnecessary. [Pg.120]

Thus, the model proposed explains the effect of CO on electric conductivity of several oxides only in case when oxygen is present in ambient volume which was observed in numerous experiments. Accordingly, the fact of existence of relatively narrow temperature interval in which an adsorbent is sensitive to CO becomes clear. This can be linked with the fact that if the operational temperature To is small the reaction products (in case of CO this is CO2) cannot get desorbed (see expression (2.80)), i.e. regeneration of the centers of oxygen adsorption is not feasible. If Tq is very high both adsorption of oxygen and reducing gas should be ruled out. [Pg.145]

The same group has looked into the conversion of NO on palladium particles. The authors in that case started with a simple model involving only one type of reactive site, and used as many experimental parameters as possible [86], That proved sufficient to obtain qualitative agreement with the set of experiments on Pd/MgO discussed above [72], and with the conclusion that the rate-limiting step is NO decomposition at low temperatures and CO adsorption at high temperatures. Both the temperature and pressure dependences of the C02 production rate and the major features of the transient signals were correctly reproduced. In a more detailed simulation that included the contribution of different facets to the kinetics on Pd particles of different sizes, it was shown that the effects of CO and NO desorption are fundamental to the overall behavior... [Pg.88]

In the third section we analyse expected effects from a microeconomic perspective, and we discuss to what extent the neoclassical microeconomic theoiy of demand is applicable to the case of pharmaceuticals. We explore the effects of co-payment on consumption and expenditure, and how it is shared between user and insurer, but also the possible effects on the health of individuals and populations. Equity considerations are inevitably raised in this analysis. The elements on which the analysis hinges in this section are price and income elasticities of demand for pharmaceuticals the role of the doctor as an inducer of demand consumer sovereignty discontinuities in demand functions and other notable exceptions to the classical ma.rgina.1ist. theoiy of demand. These exceptions require special microeconometric models and methods. [Pg.124]

In this section we examine the possible effects of drag co-payment. We analyse how it affects consumption, prices and pharmaceutical expenditure, and also how this expenditure is shared by the insurer and the patient. We study the differences and similarities between the expected effects of several forms of co-payment. By way of general reference, we present the classification devised by Murillo and Carles2 to describe the effects of co-payment on financing, use and equity of health services (Table 7.1). [Pg.127]

In order to evaluate the practical effects of co-payment it is essential to have access to quantifications of elasticities. The fourth section of this chapter deals with this. It is far from straightforward to obtain reliable estimates of the elasticities of demand for pharmaceuticals with respect to co-payment and price. Distinctions must be made between active ingredients, brands and generics, and between essential and non-essential drags, and substitution elasticities must be taken into account. [Pg.132]
