Abstract (en)
[origin: EP0053697A2] A starting reactor for the hydrogenation of coal paste, having a pressure vessel for pressures up to 700 bar, preferably up to 350 bar, bottom-end feed lines for the coal paste and hydrogen gas at temperatures from 400 to 484 DEG C, lateral lance inlet lines for hydrogen cooling gas and a top-end discharge line for the desired product in the form of vapour, the bottom product as a liquid phase and the unconverted hydrogen gas, has the following features: a) A circulation pipe (2) which is arranged centrally in the pressure vessel (1) and through which the coal paste is recycled from the top into the vicinity of the bottom-end feed lines (6, 7) for paste and gas, the feed lines (6, 7) being designed as nozzles and being in a circular arrangement around the circulation pipe (2); b) the circulation pipe (2) has a cross-section which amounts to 5 to 15% of the reactor cross-section; c) the circulation pipe (2) has a widening (3) at the top. <IMAGE>
