摘要： A process for the production of pure dimethylether by feeding the dehydration product from a dimethylether-synthesis reactor into a distillation column for the production of pure dimethylether at defined trays of this column and withdrawal of pure dimethylether and a fraction containing contaminations at defined trays of the same column, whereby in addition washing liquids and bases can be added.

摘要： This invention relates to a process for obtaining carbon black from aqueous suspension. A practically water-free carbon black is obtained from aqueous suspensions by mixing the suspension with liquid low-boiling hydrocarbons, then expanding the mixture in a vessel to evaporate the hydrocarbons, then drawing off separately the hydrocarbon vapors carrying the carbon black and the remaining liquid aqueous phase from the vessel, and separating the carbon black from the hydrocarbon vapors.

摘要： In a process for the production of pumpable coal slurries for use in high-pressure hydrogenation, such an amount of finely divided coal is mixed into an oil which boils at a temperature of higher than about 200.degree. C., as not to exceed the limit of pumpability in respect of the slurry produced. The slurry is treated for about 0.5 to 15 minutes at a temperature of from 280.degree. to 450.degree. C., possibly under elevated pressure. Such a further amount of finely divided coal is mixed into the slurry after the above-indicated treatment, that the limit of pumpability is once again not exceeded. After the addition of the further amount of finely divided coal, the slurry can optionally be subjected again to heat treatment. This mode of operation permits the production of slurries with an elevated coal content, without coking occurring or pumpability being lost when the slurries are heated to hydrogenation temperature.
