RAG/STEAG Large Pilot Plant for the Catalytic Hydrogenation of Pit Coal

摘要

The Ruhr Coal AG and Steag AG working within the framework of the ''Energy Technology Programme'' of the Land Nordrhein-Westfalen have undertaken the development to a commercially usable state of a coal hydrogenation process to produce coal oil based on a catalytic method. The project has evolved from preliminary studies and tests in the laboratory and on a technical scale up to the planning of a large pilot plant which is expected to go into operation in 1980 and have a coal throughput of 200 t (free of water and ash)/d. The IG process was further developed and optimized as a basis for the hydrogenation. The hydrogen used for hydrogenation is taken from a steam reformer plant operated with liquid gas. The processing plants consist of plants for coal preparation, hydrogenation, atmospheric distillation, vacuum distillation, pressure-releasing evaporation, residue disposal and furthermore of the ancillary plants for gas post-processing, process-water processing, and hydrogen generation and a series of operational means and side-plants. Optimization investigations on a technical scale are being done on the further processing of coal oil to chemical raw materials. (ERA citation 04:025167)
