       Deals with the low-temperature carbonization plant, the Lurgi high-pressure gasification plant, and the experimental high-pressure Fischer-Tropsch plant.  The carbonizing plant is the standard Lurgi “Spulgas” design.  Its primary object was to produce tar for hydrogenation in the adjoining Brabag I plant.  The Lurgi high-pressure gasification is comparable to that from low-temperature carbonization.  The fuel must not cake during carbonization.  The carbonized fuel passes down into the combustion zone in the base of the generator where it reacts with steam and O₂.  As the gases ascend through the fuel in the combustion zone, it is cooled and reactions leading to the formation of CH₄ occur.  Analyses of the gas range 10-25% CH₄.  All solid noncaking fuels are suitable for pressure gasification, such as brown coal or lean hard coal.  Artificial aging can be used to reduce the caking properties of coals which are unsuitable without treatment.
