Abstract (en)
[origin: US4639310A] A process for the production of reformer feed and heating or diesel oil from coal which comprises introducing a pulverized coal-oil slurry together with a hydrogenation gas into a liquid-phase hydrogenation stage; remoping solids-containing residue from the discharge from the liquid phase hydrogenation stage, cooling the resulting residue-free volatile coal-oil fraction from the discharge and, if necessary, removing a slurry oil fraction therefrom before feeding the volatile coal-oil fraction to a gas-phase hydrogenation stage; introducing fresh hydrogen which is substantially free of contaminants into the gas-phase hydrogenation stage together with the volatile coal-oil fraction, the fresh hydrogen introduced into the gas-phase hydrogenation stage constituting the entire amount of hydrogen required for the process; and utilizing the waste-gas from the gas-phase hydrogenation as the hydrogenation gas for the liquid-phase hydrogenation. By contrast with conventional processes, which during gas-phase hydrogenation requires operating partial pressures of 300 bars, the process of this invention makes possible the lowering of the operating pressures required during gas-phase hydrogenation to approx. 50-200 bars and also enables significantly reduced consumption of hydrogen.
