Schematic drawing of a gas discharge tube in operation. When a high voltage is applied to the two perforated plates, an electrical discharge occurs between them. The positively charged and negatively charged particles that form in the gas move to collectors at the ends of the tube.

Figure 2.4. Schematic drawings of a cylindrical flow reactor and a batch reactor. In the ideal case the flow reactor operates as a plug-flow reactor in which the gas moves as a piston down through the tube, whereas the ideal batch reactor is a well-mixed Tank Reactor...

Figure 8.22. Schematic drawing of an adiabatic two-bed radial flow reactor. There are three inlets and one outlet. The major inlet comes in from the top (left) and follows the high-pressure shell (which it cools) to the bottom, where it is heated by the gas leaving the reactor bottom (left). Additional gas is added at this point (bottom right) and it then flows along the center, where even more gas is added. The gas is then let into the first bed (A) where it flows radially inward and reacts adiabatically whereby it is heated and approaches equilibrium (B). It is then cooled in the upper heat exchanger and move on to the second bed (C) where it again reacts adiabatically, leading to a temperature rise, and makes a new approach to equilibrium (D).

Figure 5.5 Volumetric density of compressed hydrogen gas as a function of gas pressure including the ideal gas and liquid hydrogen. The ratio of the wall thickness to the outer diameter of the pressure cylinder is shown on the right-hand side for steel with a tensile strength of 460 MPa. A schematic drawing of the pressure cylinder is shown as an inset.

A carbon-deposited film was prepared from the alumina film with 30-nm channels by the CVD technique using propylene. Fluorination was carried out by direct reaction of the film with dry fluorine gas (purity 99.7%). The film was placed in a nickel reactor and was allowed to react with 0.1 MPa of fluorine gas for 5 days at a predetennined temperature in the range of 50 to 200°C. Then the fluorinated carbon nanotubes were separated by dissolving the alumina film with HF. A schematic drawing of the fluorination process is given in Fig. 10.1.15. 

Ebsworth and coworkers have determined the structures of trimethyl(methylene)phos-phorane (29)60, trimethyl(silylmethylene)phosphorane (30)61 and hexamethylcar-bodiphosphorane (31 )38 in the gas phase using electron diffraction techniques. A summary of some of their results is given in Table 6 and schematic drawings of these structures are given in Figure 8. 

Schematic drawings of some typical modem furnace black reactors are shown in Figure 50. They all have a gas-tight metal jacket. The reaction zone is coated with a ceramic inner liner, generally on an alumina base, which is stable to temperatures of ca. 1800 °C. Several quenching positions allow the changing of the effective volume of the reactor. This allows variation of the mean residence time of the carbon black at the high reaction temperature. Typical residence times for reinforcing blacks are 10-100 ms.

Fig. 5.7. Liquid nitrogen storage Dewars, (a) Atmospheric-pressure Dewar. Liquid nitrogen is drawn from the Dewar by applying a small positive pressure of nitrogen gas to the inlet on the sleeve of the metal dip-tube, forcing liquid nitrogen out the dip-tube. (f>) Schematic drawing of a pressurized storage Dewar. Spigots arc generally provided for both liquid and gas withdrawal.

In one of the most common sensors, the non-porous solid electrolyte layers takes the form of a crucible closed at one end so that air used as a reference gas can be introduced into the interior of the crucible while the outside of the crucible is exposed to the exhaust gas. A schematic drawing and E versus the air-fuel ratio curve for this sensor are shown in Figure 1. E is the electromotive force (EMF) between the two electrodes in accordance with the Nemst equation ...

Figure 5.28 Schematic drawing of the limitation of the source volume by two conical diaphragms (D). The cones are aligned with their axes around the direction of the incident photon beam which enters the cone on the left-hand side and leaves the cone on the right-hand side. The cone on the left-hand side also serves as the inlet for the target gas as indicated in the figure. Electrons produced in the source volume between the cones can fly towards the electron spectrometer. From [KSc93].
