Abstract

After reviewing briefly the situation of Germany’s gas demand and supply which makes it highly desirable to set free larger amounts of coke-oven gas by firing coke ovens with producer gas, the general program of research and development of the Ruhrgas A-G is explained. Main efforts were directed toward the development of two gas producers using low-grade pulverized coal or coal dust obtained from the coal-cleaning operations. The first process, involving gasification of pulverized coal in a vortex-type system, with slagged-ash removal, has reached the state of commercial applicability, and the results obtained exceed those of conventional gas producers gasifying coke. The second process described in some detail, the coal-dust pulse-jet gasifier, is in the experimental stage, but already has shown promising results. Further work is in progress to improve operations and efficiencies.
