Definitions
- a known method of processing oil shale including heating fine-grained shale with a solid heat carrier to form a vapor-gas mixture, which after dry cleaning of mechanical impurities is cooled by irrigation with the recirculating part of the heavy resin released during cooling of the vapor-gas mixture, the removal of non-condensed vapors with their subsequent separation into medium, light and gasoline fractions of tar (oil), tar pitch and semi-coking gas (see Chemistry and technology of shale tar, edited by N.I. Zelenin. L., published by Chemistry, 196 8, p. 77-78).
- the method is as follows.
- Shale or other high-ash fuel after crushing to a fraction of O-20 mm. is fed by a screw feeder to dryer 1, where it is dried as a result of contact with exhaust flue gases.
- the air suspension of dry shale and flue gas is separated into cyclone 2 and fed by a screw feeder to mixer 3, where it is mixed with a coolant and sent to a rotating reactor 4.
- High ash oil (up to 30% ash) is fed directly to the reactor inlet from the bottom of the rotor film evaporator.
- thermal decomposition (pyrolysis) of the organic part of high-ash fuel occurs.
- the reaction products enter the dust collection chamber 5, equipped with cyclones, where they are separated into a coke-ash residue and a gas-vapor mixture.

Abstract
Le procédé de transformations des fractions légères de combustibles à haute teneur en cendres y compris les schistes bitumineux et la lignite comprend la pyrolyse de la partie organique du combustible solide à haute teneur en cendres et sa séparation en résidu de coke et de cendres et un mélange gaz-vapeur. La nouveauté consiste en ce que pour purifier l'huile de circulation lourde des cendres on utilise dans le système de condensation de mélange de gaz et de vapeur un évaporateur à rotor et à film, et l'huile à haute teneur en cendres qui se forme est dirigée vers une opération de pyrolyse secondaires directement dans le réacteur. Cela permet d'obtenir un produit commercialisable à faible teneur en impuretés de cendres (moins de 0,02 %) sans dépenses supplémentaires pour l'organisation de filtrage et d'ensevelissement des restes, d'augmenter la production des fractions légères d'huiles de schiste et d'évacuer les cendres selon un schéma standard.
