METHOD AND DEVICE FOR CONDUCTING ENDOTHERMAL GAS-PHASE OR GAS-SOLID REACTIONS Russian patent published in 2021 - IPC B01J8/04 B01J19/24 

FIELD: gas-solid-state reactions.

SUBSTANCE: inventions group relates to a reactor and a method for conducting endothermic gas-phase or gas-solid-state reactions. The method includes carrying out an endothermic reaction at the stage of product formation in a first zone of the reactor, a product formation zone filled with pre-heated solid particles, removing a gas stream containing the product and passing it through a second zone of the reactor, a heat recovery zone, and the heat of the gas stream containing the product, accumulates in a fixed bed, introducing heat into the heating zone, which is located between the product formation zone and the heat recovery zone, passing the purge gas in the same direction during the cleaning stage and passing the gas in the regeneration phase in the opposite direction, while the method is carried out cyclically.

EFFECT: proposed concept of the method for conducting the reactions provides the possibility of an operation mode with integrated reverse heat exchange, excludes the use of fittings in the hot area of the technological space and excludes contamination.
