The present disclosure relates to the field of reactor technologies and in particular to a solid-liquid phase reactor for preparing a powder product, which includes a vessel shell, a material-restricting partition net, a solid reactant charge opening, and a reaction solution make-up opening. The material-restricting partition net is disposed in a cavity of the vessel shell and connected to the vessel shell. The material-restricting partition net is enclosed to form a semi-closed material-restricting zone with an upward-facing opening itself or together with an inner wall of a vessel. A frame of the semi-closed material-restricting zone is rigid. The solid reactant charge opening is in communication with the facing-up opening of the semi-closed material-restricting zone, and the reaction solution make-up opening is in communication with an internal space of the semi-closed material-restricting zone.

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 (E1, E2), positioned on a transport line carrying particles circulating between a reduction zone (210) and an oxidation zone (200) 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.
