Haldor Tops e have described a number of sulphur resistant catalyst formulations.131 132 For example, metals of Groups VB or VIB with Fe, Co, or Ni on a porous ceramic (A1203 or Ti02) as support can give gases containing large amounts of hydrocarbons in addition to methane in the...

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).
