Pure uninhibited tetrafluoroethylene can polymerise with violence, even at temperatures initially below that of room temperature. There is little published information concerning details of commercial polymerisation. In one patent example a silver-plated reactor was quarter-filled with a solution consisting of 0.2 parts ammonium persulphate, 1.5 parts borax and 100 parts water, and with a pH of 9.2. The reactor was closed and evacuated, and 30 parts of monomer...

In the following part, four reactors that have been extensively studied in our lab are described the open plate reactor (OPR) - the Alfa-Laval reactor technology (ART ) plate reactor, the Shimtec reactor from Chart Industries, the Corning (glass reactor), and the DeanHex reactor which has been constructed with SiC and stainless steel.

The radio-frequency glow-discharge method [30-34] has been the most used method in the study of a-C H films. In this chapter, it is referred to as RFPECVD (radio frequency plasma enhanced chemical vapor deposition). Film deposition by RFPECVD is usually performed in a parallel-plate reactor, as shown in Figure 1. The plasma discharge is established between an RF-powered electrode and the other one, which is maintained at ground potential. The hydrocarbon gas or vapor is fed at a controlled flow to the reactor, which is previously evacuated to background pressures below lO"" Torr. The RF power is fed to the substrate electrode...

In electrochemical reactors, the externally imposed velocity is often low. Therefore, natural convection can exert a substantial influence. As an example, let us consider a vertical parallel plate reactor in which the electrodes are separated by a distance d and let us assume that the electrodes are sufficiently distant from the reactor inlet for the forced laminar flow to be fully developed. Since the reaction occurs only at the electrodes, the concentration profile begins to develop at the leading edges of the electrodes. The thickness of the concentration boundary layer along the length of the electrode is assumed to be much smaller than the distance d between the plates, a condition that is usually satisfied in practice.

The initial conditions are at t = 0, T = To, andp = 0. The parameter n characterizes the dimensions of the volume for a parallel plate reactor n = 0 for a cylindrical reactor n = 1 and for a spherical reactor n = 2. In these equations, x is a space coordinate A. is the coefficient of thermal conductivity r is the characteristic size of the reactor k is the heat transfer coefficient and To is the initial temperature of the initial medium. 

Figure 2.22. Experimental data (points) and calculated curves (solid lines) for changes in the degree of crystallinity in the center (curves 1 and 2) and at the wall (curves 3 and 4) of a plate reactor. The width of the plate is 32 mm. Tsur = 140°C.

An example illustrating the results of calculations for the dependencies T(t) and a(t) is shown in Fig. 2.22 for two locations the center of the plate (zo = 16 mm) and its surface. Experimental points are also marked.97,99 The evolution of the spatial distribution of the crystallinity in a plate reactor is shown in Fig. 2.23. Comparison of the calculated curves and experimental points confirms that the theoretical model is correct and that the results reflect all the main features of the real situation, including the slight curvature and the plateau in the T(t) dependence.

One of the benefits of applying micro structured heat exchanger/reactors is the potential of combining an endothermic reaction such as steam reforming with an exothermic reaction such as catalytic combustion. This idea was proposed for the macro scale as a so-called catalytic plate reactor (CPR) by Reay [100],...
