The invention is a method for chemical looping (CLC) oxidation-reduction combustion of liquid hydrocarbon feedstocks carried out in a fluidized bed. A liquid hydrocarbon feedstock () is partly vaporized on contact with a hot particle solid () to form a partly vaporized liquid feedstock and to form coke on the solid prior to contacting partial vaporized liquid feedstock () with a redox active mass of particles () to achieve combustion of the partially vaporized liquid feed (). The hot solid particles can notably be from a second fluidized-bed particle circulation loop.

The invention relates to a process and to a unit for chemical looping oxidation-reduction combustion of a hydrocarbon feed, wherein heat exchanges are controlled through a level variation of a dense fluidized bed of active mass particles in an external heat exchanger (E, E), positioned on a transport line carrying particles circulating between a reduction zone () and an oxidation zone () for the particles in the chemical loop. The bed level variation is allowed through controlled application of a pressure drop on a fluidization gas outlet in the heat exchanger, said pressure drop being compensated by the level variation of an active mass particle bed in a reservoir zone provided on the particle circuit in the chemical loop.
