This short report compared three coal liquefaction plants in Germany which operated principally on bituminous coal and which had been built a few years apart in time. From the earliest plant (Scholven) to the latest (Blechhammer), the liquid-phase throughput had been almost tripled, partly because of the change from 300-atm to 700-atm operation, and partly because of the use of heat exchange to heat the coal paste part way to reaction temperature. This introduction of coal paste heat exchange reduced the load on preheaters so much that the amount of heat necessary in the preheater to heat one (metric) ton of coal paste to reaction temperature was reduced from 320,000 kcal to 170,000 kcal. Another development in the middle plant (Gelsenberg) was the addition of a portion of the cold coal paste at the input to the second reaction oven in each chamber, letting the heat of reaction itself heat that paste to reaction temperature (and at the same time regulating the temperature of the reaction better). Finally it was noted that for the production of a given amount of synthetic fuel, Blechhammer needed only about half as many reaction chambers as did Scholven.
