Distilling shale

Abstract

Light paraffin oils and other oils for motors are obtained from shale, and benzene, toluene, and solvent naphtha are obtained from coal by a process in which the coal or shale is preferably powered to pass through a mesh of 64 to the inch and is heated with a mixture of finely ground carbonate or the like which under the action of heat gives off carbonic acid, and with small iron scrap or its equivalent which is adapted to increase the volume of hydrocarbons evolved. The temperature of the retort is maintained between 175 and 800/sup 0/C., and after all the vapors are given off at the higher temperature a fine jet of water may be injected into the retort and the temperature increased. The produced oil is condensed and purified by fractional distillation, and the gas formed is stored after passing it through a tower packed with coke saturated with a non-volatile oil with recovery of an oil of light specific gravity which is condensed in the tower. The residuum from the still in which the produced oil is fractionated may be treated with carbonate and iron, as in the first stage of the process, and the distillate therefrom  More>>

The residuum from the still in which the produced oil is fractionated may be treated with carbonate and iron, as in the first stage of the process, and the distillate therefrom passed to a second retort containing manganese dioxide and iron scrap preferably in the proportion of one part or two. The mixture, e.g., one containing shale or oil with six to thirteen percent of oxygen, to which is added three to eight per cent of carbonate, and from one and a half to four per cent of scrap iron, is conveyed by belts and an overhead skip to a hopper of a retort in a furnace heated by burners supplied with producer gas. The retort is fitted with a detachable lid and the vapors formed are led by a pipe to a vertical water-cooled condenser with a drain-cock which leads the condensed oils to a tank, from which a pipe leads to a packed tower for removing light oils and from which the gas passes to a holder.}
