Folded plate reactor

Lopez et al. [166] described the operation of their mesoscaled folded-plate reactor which was operated with water cooling in a cocurrent flow arrangement, with four stages of air addition (Figure 14.24). Their Au catalyst was operated well below 100°C at an O/CO ratio of 3. The CO could be reduced to values below 100 ppm and the reactor had 0.4-0.6 kW electric power equivalent.

Folded plate structures — stripes of plate jointed at the edges — are not really shells at all, but in functioning and in the way they can be treated are quite close to cylindrical shells. The edges of the dome shell of the reactor vessel will, sometimes, develop the shape of the folded plates. 

Implementation of the above screening principle requires three main parts a thermosensitive IR camera capable of recording heat emissions of the catalysts contained in the reactor system, the reactor itself as central part and an xyz-posi-tionable sampling capillary, connected to the second analytical tool (MS or GC, etc.) (Fig. 2.4). To simplify matters, a reactor with a 4x4 matrix of reaction channels is illustrated here, the actual reactor formats used at hte Aktiengesellschaft are 96- and 192-fold reactor systems based on the 8xl2-MTP (micro-titer plate) matrix.
