Abstract
The invention relates to a method and to a device for chemical looping combustion CLC of a solid hydrocarbon feed wherein it is proposed to inject the solid hydrocarbon feed so as to limit any occurrence of sticking of the feed to the walls of the injection device. The solid feed is fed into a conveying zone operating under fluidized bed conditions and opening into a combustion reactor. A fluidization gas is injected into this conveying zone while controlling the flow of gas in such a way that the superficial velocity of the gas in the conveying zone is higher than the terminal velocity of the solid hydrocarbon feed particles and the terminal velocity of solid particles present in the combustion reactor, and while controlling the fluidization gas temperature in such a way that the temperature in the conveying zone is less than or equal to 500° C.
