Abstract: The present invention provides a hydrogenation process for reprocessing used oil into secondary raffinates in the form of lubricating oils. In this process according to some embodiments of the invention, ecologically undesirable byproducts or waste materials are eliminated, without requiring expensive and time-consuming separation stages or reaction conditions, or the use of expensive catalysts. In particular, even severely contaminated oils, i.e. those which contain organo-chlorine compounds, in particular PCB, chlorinated dioxins and dibenzofurane in concentrations above certain limits, can also be reused as secondary raffinates, in particular as lubricating oils. No longer need these substances be destroyed in a high temperature combustion process, for example. As a first step, the coarse solid substances are removed from the used oil. Thereafter, with the addition of hydrogen, a hydrogenation step is conducted in a sump phase at predetermined pressures and temperatures.

Abstract: The preferred invention describes a process for the hydrogenation of organochlorine compounds and a neutralizing agent for hydrochloric acid which is obtained from organochlorine compounds.

Abstract: 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.

Abstract: Disclosed is a process for improving the yield and hydrogen production of catalytic reforming of gasoline derived from mineral oil sources, which at the same time improves knock resistance of the fuel derived. A positive amount of coal-derived feedstocks including refined light coal oil, light oil derived from coal mineral oil refining, gasoline derived from hydrocracking of coal mineral oil and the top product of coal hydrogenation are added to the conventional mineral oil-derived feedstock. An improvement in catalyst residence time is also achieved.
