Once the above-discussed components of the model have been determined, they are added to the final model of a monolith (or even filter) reactor. The monolith reactor model has already been described in Section III. The next stage is to validate the model by comparing the predictions of the model based on laboratory data, with the real-world data measured on an engine bench or chassis dynamometer. At this stage the reason(s) for any discrepancies between the prediction and experiment need to be determined and, if required, further work on the kinetics done to improve the prediction. This process can take a number of iterations. Model validation is described in more detail in Section IV. D. Once all this has been done the model can be used predictively with confidence. 

In 1992, a rather unusual furfural plant was built. With a front end according to the AGRIFURANE process described in chapter 10.2, the back end was designed as shown in Figure 112. The filtered reactor condensate containing 5 % furfural, 1.7 % acetic acid, 0.17 % formic acid, and various low boilers was introduced into an extraction tower 1 fed with chloroform at the top. On the way downwards, the heavy chloroform (density 1.498 g/cc at room temperature) picked up the furfural, and in view of the poor solubility of chloroform in water, it formed a chloroform/furfural extract at the bottom. This extract entered a distillation column 2 removing the chloroform as the head fraction. From a buffer tank 3, this chloroform was recycled to the extraction tower 1. The sump fraction of the distillation column 2 consisted of furfural, polymers, waxes, and some low boilers. This fraction was introduced into a distillation column 4, which yielded a head fraction of low boilers, a side stream of furfural, and a sump fraction of polymers and waxes. 

Both trichloroethylene (TCE) and toluene were found to have inhibitory effects on the degradation of MTBE in FBRs due to a form of competition. The authors further stated that the high loading rates of TCE and toluene may not have been the only factor leading to inhibition [85]. Inhibition of MTBE degradation by BTEX was observed in a trickhng filter reactor which had a MTBE degrading strain involved in direct metabolism. It was not identified what mechanism was responsible for the inhibition [79].

Procedure for determining quantum yield of a photochemical reactor The set-up of the apparatus has been discussed above. The choice of light source, filter, reactor cell and detector depends upon the wavelength range used for the photochemical reaction.
