The kinetics of a complex catalytic reaction can be derived from the results obtained by a separate study of single reactions. This is important in modeling the course of a catalytic process starting from laboratory data and in obtaining parameters for catalytic reactor design. The method of isolation of reactions renders it possible to discover also some other reaction paths which were not originally considered in the reaction network.

An economic benefit can occur through the retrofitting of a catalytic reactor, designed to perform partial destruction of the hypochlorite, into a plant already equipped with a chemical treatment system. The savings in chemicals consumption can more than offset the capital investment associated with the catalytic reactor and purchase of the initial catalyst charge. At high feed concentrations, say above a few weight per cent, the payback time can in fact be less than six months. 

Chemical vapor deposition and heterogeneous catalysis share many kinetic and transport features, but CVD reactor design lags the corresponding catalytic reactor analysis both in level of sophistication and in scope. In the following we review the state of CVD reactor modelling and demonstrate how catalytic reactor design concepts may be applied to CVD processes. This is illustrated with an example where fixed bed reactor concepts are used to describe a commercial "multiple-wafers-in-tube" low pressure CVD reactor.

Figure 10-7 Collecting information for catalytic reactor design.

Example 10-3 illustrated the major activities pertinent to catalytic reactor design described earlier in Figme 10-7. In this example the rate law was extracted directly from the data and then a mechanism was found that was consistent with experimental observation. However, developing a feasible mechanism may guide one in the synthesis of the rate law. 

This is the conversion that will be achieved in a batch reactor for a first-order reaction when the catalyst decay law is second-order. The purpose of this example was to demonstrate the algorithm for isothermal catalytic reactor design for a decaying catalyst.

Catalyst deactivation is always a problem in catalyst and catalytic reactor design. Empirical equations to represent deactivation rates in design calculations are reported by Weekman (1968), Sadana and Doraiswamy (1971), and Doraiswamy and Sharma (1984). Here, we briefly touch upon the...
