REACTOR FOR THERMAL DECOMPOSITION OF SOLID COMBUSTIBLE MINERALS Russian patent published in 2008 - IPC C10B53/06 C10B49/00 

FIELD: oil and gas industry.

SUBSTANCE: invention can be employed in chemical and fuel processing industries at production of artificial liquid and gaseous fuel or substitute of oil. Combustible shale is batched into a case 1 of the reactor from a loading hopper 6. A rotating worm 2 propels combustible shale along the case 1 heated to 400-450°C and simultaneously mixes shale. As result of combustible shale contact with a heated wall of the case 1 of the reactor there occurs thermal decomposition of particles of powder fraction of combustible shale with formation of steam-gas mixture consisting of shale oil, shale gas and pyrolised water. Steam-gas mixture is sucked off via an exhaust channel 7. After pyrolysis heated semi-coke is thrown through a pressurised chamber 5 into a receiving hopper 8 for its further after-burning in a fire chamber 9. An air-blower 10 charges air into the fire chamber 9 and further smoke gases of a heat carrier come into a shell 3 of the case 1 of the reactor for pyrolysis implementation.

EFFECT: producing saturated steam-gas mixture with reduced power consumption due to utilisation of exhaust gases, also reducing specific amount of metal in facility.
