2018-1-2 · Exemplarily, the reduction of 2-octanone to (R)-2-octanol by a recombinant Escherichia coli in a biphasic ionic liquid/water system was studied in a miniaturized stirred-tank bioreactor system allowing the parallel operation of up to 48 reactors at the mL-scale. The results were compared to those obtained in a 20-fold larger stirred-tank reactor.
Residence time distribution of catalyst particles in a continuous flow stirred vessel plays an important role in determining the final particle size distribution in processes where product is .

The Process Flow Diagram for the integrated process is shown in Figure 5.5. From Figure 5.5, it can observed that the pairing between the nearest hot and cold stream is performed whenever possible. At the same time, considerations were also taken when pairing streams to .
The flow structure of a continuous-flow reactor stirred by a Rushton turbine was investigated by laser Doppler velocimetry for two different mean residence time-mixing time ratios.

An example which brings in somewhat different requirements is the spark plug of an internal combustion engine (Figure 1.4). The spark electrodes must resist thermal fatigue (from rapidly fluctuating temperatures), wear (caused by spark erosion), and oxidation and corrosion from hot upper-cylinder gases containing nasty compounds of sulphur.

Figure 7 shows tlae agreement between the sample LO curve and the calculated LO curve in plug flow and mixed flow. The adjusted E'a is close to Ea, and the zero-order frequency factor is close to that given by (5). The model curve for adiabatic plug flow is given by the solution, XCO, of (see appendix): CO d___X= ~ k' (T)H(1 - X) t0 dz z = 0, X = 0
