Fig. 10.15 Multiple steady states of the TAME process. Comparison between theoretical predictions (top) and experimental results (bottom)

demonstrated that the column operating at the low steady state is shifted into the higher steady state after a pulse injection of pure TAME for a short period. This dynamic behavior was reproduced with dynamic simulation of a detailed non-equilibrium model by Baur et al. [7] (see also Chapter 9).

Comparison between theoretical predictions and experimental results showed, that, in contrast to the MTBE process, transport processes inside the catalyst were negligible for the TAME process. This is again due to the fact that the microkinetic rate of reaction is one order of magnitude slower than in the MTBE case and is therefore dominating for the operating conditions considered in this study. This was confirmed more rigorously in a recent paper by Higler et al. [39].
