Leakage reaction

If the product B is involved in a leakage reaction to yield an undesired product C with a rate constant k, Eq. (4) can be rewritten ... [Pg.3761]

This suggests that even if the supercapacitor is fully charged, extra current density is still needed to overcome the self discharging caused by R. However, if the leakage reaction does not occur, i ai can be simplified... [Pg.70]

In this way the entire capacitance of fhe elecfrode layer should be the sum of fhese fwo capacifances. If fhere is no parallel leakage reaction or its reaction kinetics are fairly slow, R, °° and fhe EC in Figure 7.10a can be simplified as shown in Figure 7.10b. If fhe pseudocapacifance-generating electrochemical reaction kinetic activity is fairly slow, R °° and Cp —> 0 and the EC in Figure 7.10a will be reduced to Figure 7.10c Moreover, if there are no parallel... [Pg.296]

Calculated Nyquist plots according to Equation (7.28) to show effects of parallel leakage reaction resistance (Rp). The magnitudes of other parameters are also shown. [Pg.300]

The nuclear chain reaction can be modeled mathematically by considering the probable fates of a typical fast neutron released in the system. This neutron may make one or more coUisions, which result in scattering or absorption, either in fuel or nonfuel materials. If the neutron is absorbed in fuel and fission occurs, new neutrons are produced. A neutron may also escape from the core in free flight, a process called leakage. The state of the reactor can be defined by the multiplication factor, k, the net number of neutrons produced in one cycle. If k is exactly 1, the reactor is said to be critical if / < 1, it is subcritical if / > 1, it is supercritical. The neutron population and the reactor power depend on the difference between k and 1, ie, bk = k — K closely related quantity is the reactivity, p = bk jk. i the reactivity is negative, the number of neutrons declines with time if p = 0, the number remains constant if p is positive, there is a growth in population. [Pg.211]

However, the reaction with water can be made to be extremely slow. Because the alkaline electrolyte is corrosive toward human tissue as well as toward the materials ia devices, it is more important to have a good seal toward preventing electrolyte leakage ia an alkaline battery than ia a carbon—2iac cell. The formation of a good seal is, however, iacompatible with the formation of a noncondensable gas like hydrogen. [Pg.524]

The control of leakage loss across die blades in a reaction expander is extremely important. Maintaining adequate clearance implies preventing mechanical rubs while at die same time minimizing die loss effect on expander efficiency. [Pg.227]

Monitor stock, e.g. temperature, pressure, reaction, inhibitor content, degradation of substance, deterioration of packaging or containers/corrosion, leakages, condition of label, expiry date, undesirable by-products (e.g. peroxides in ethers) Spillage control bund, spray, blanket, containment. Drain to collection pit Decontamination and first-aid provisions, e.g. neutralize/destroy, fire-fighting Contain/vent pressure generated to a safe area... [Pg.248]

Air in leakage, depending on the quantity, can create an explosive mixture in some process reaction systems therefore, the system should be tested for air leaks and kept as tight as practical. [Pg.344]

As particle size decreases, hydrogen leakage decreases and hot spot temperature in the bed is higher. Thus the smaller particle size has greater activity (see Table VI). A kinetic system which defines the reaction in terms of CO and C02 methanation and CO shift conversion was used to determine the activity (see last column of Table VI). [Pg.60]

In the various laboratory studies when the outlet gas composition was not at equilibrium, it was observed that the steam-to-gas ratio (S/G) significantly affected the hydrogen leakage while the carbon monoxide still remained low. On the assumption that various reactions will proceed at different rates, a study was made to determine the effect of S/G on the reaction rate. The conditions for this test are presented in Table VII the findings are tabulated in Table VIII. [Pg.61]
