The coal liquefaction project in the Coal Oil Plant in Bottrop, West-Germany, pursued the following targets: demonstration of the improved Bergius-Pier hydrogenation technology on a technical scale; testing and further development of process-related and mechanical components, identification of environmental impact, development of design data base for a commercial unit, and generation of technical and operational know how. The Pilot plant in Bottrop with a capacity of 200 t maf coal/day was erected in order to meet these targets. In this project phase the program focussed on the primary conversion of coal, using liquid phase hydrogenation reactors. This procedure yielded a raw oil from coal in the boiling range of naptha and mid distillate, which was highly aromatic and had high contents of oxygen and nitrogen compounds. Secondary upgrading processes were applied in process development units, in order to convert the primary products into marketable fuels, e.g. gasoline, heating oil, kerosene and diesel fuel. Each of the different upgrading routes included severe hydrotreating as first step. For this reason, the hydrotreating reactors were in 1986 directly linked to the primary conversion system as shown in the simplified flow scheme. Contrary to the first mode of processing in which the net product fractions - naphta and middle distillate were subjected to upgrading processes in separate units, the total vaporised effluent from the liquid phase reactors including the vacuum gasoil fraction is in the integrated alternative fed to the hydrotreating stage, the so called ''gasphase reactors''.
