Abstract
The condensible parts are removed from the distillation gas of oil shale, a portion of the remaining amount of gas is removed and the rest is heated, e.g., by the combustion gas of the distillation residue and used without the addition of any more materials to distill oil shale. The installation for this consists of a distillation cyclone reactor, whose gas outlets are connected to an oil separator and whose tangential feed nozzles are connected by way of a blower and a heat exchanger to the oil separator.
