Data processing theory, parameters

Table 1 presents several examples of unsteady-state kinetics models. These models are presented in the form of rate dependencies for catalytic reaction stages and side processes. The parameters of the models, such as reaction rate constants and activation energies, are given in references (Table 1) and were determined mainly from experimental data using transient response techniques. For the reaction of CO oxidation over a supported platinum catalyst, the kinetic gas theory was applied for estimating the adsorption constants. 

The theory of process and computer control is relatively simple. The processing of parameters is measured and translated into computer language. The computer then compares the actual data with the programmed data.

There is considerable scope for alternative explanations (see Sect. 3.6.3, 3.7, and 4). Most of the deductions from the data ignore the variation in tre due to the kinetic nature of the process, despite claims within the theory that this should have a large effect [122]. Equilibrium uncertainties as described in Sect. 2.3 are completely ignored. When the parameters within LH theory are also considered it no longer seems surprising that self-consistency can be obtained.

The main goal of this chapter is to review the most widely used modeling techniques to analyze sorption/desorption data generated for environmental systems. Since the definition of sorption/desorption (i.e., a mass-transfer mechanism) process requires the determination of the rate at which equilibrium is approached, some important aspects of chemical kinetics and modeling of sorption/desorption mechanisms for solid phase systems are discussed. In addition, the background theory and experimental techniques for the different sorption/ desorption processes are considered. Estimations of transport parameters for organic pollutants from laboratory studies are also presented and evaluated.
