Capacity predicting

When the values of the BET monolayer capacity calculated from Type III isotherms are compared with independent estimates (e.g. from nitrogen adsorption) considerable discrepancies are frequently found. A number of typical examples are collected in Table 5.1. Comparison of the value of the monolayer capacity predicted by the BET equation with the corresponding value determined independently (columns (iv) and (v)) show that occasionally, as in line 6, the two agree reasonably well, but that in the majority... 

This model, the Einstein model for heat capacity, predicts that the heat capacity is reduced on cooling and that the heat capacity becomes zero at 0 K. At high temperatures the constant-volume heat capacity approaches the classical value 3R. The Einstein model represented a substantial improvement compared with the classical models. The experimental heat capacity of copper at constant pressure is compared in Figure 8.3 to Cy m calculated using the Einstein model with 0g = 244 K. The insert to the figure shows the Einstein frequency of Cu. All 3L vibrational modes have the same frequency, v = 32 THz. However, whereas Cy m is observed experimentally to vary proportionally with T3 at low temperatures, the Einstein heat capacity decreases more rapidly it is proportional to exp(0E IT) at low temperatures. In order to reproduce the observed low temperature behaviour qualitatively, one more essential factor must be taken into account the lattice vibrations of each individual atom are not independent of each other - collective lattice vibrations must be considered. 

Stupin and Kister (loc. cit.) relate the flattening of the curve in Fig. 14-76 at low liquid loads to the formation of more, smaller, easier-to-entrain liquid drops when the liquid load is lowered beyond the limiting liquidload. It follows that devices that can restrict the formation of smaller drops may be able to approach the system limit capacity predicted by Stupin s original equation [Eq. (14-167)] even at low liquid loads. 

The removal of organics (typically measured by total organic carbon or TOC), is an adsorption process. The surface of activated carbon is both hydrophobic and oleophilic, conditions favorable for good removal of TOC. The capacity for organics is a function of temperature, pH, nature of the organic, and concentration such that accurate capacity predictions are not possible. However, typically 25% to 80% of TOC is removed through a carbon filter.

Answer by author The comment is well taken. The authors would like to re-emphasize that the capacities predicted from these experimental data are in close agreement with observed purifier capacities for nitrogen in the National Bureau of Standards hydrogen liquefier.

An example of a protein for which the calculated and measured Cp i) T) are very similar has been given by Schoppe et al. [2] (Figure 6). The heat capacity predicted from the model peptides [29,30] shows only minor deviations from the experimental curve. In contrast, calculations based on parameters derived from the small organic model compounds [28] provide much lower values.
