Device for chemical looping combustion in liquid medium

A device for chemical looping combustion of a fuel, comprising:

• at least one tank arranged to receive a liquid comprising at least one oxidizing agent and at least one reducing agent together forming at least one redox couple,
• an oxidation loop comprising:
• a first conduit comprising a first inlet opening into the tank, arranged to take in a first part of the liquid comprising at least the reducing agent, and a first outlet,
• a first injection device, connected to a first supply of a first driving fluid comprising dioxygen, and arranged to introduce the first driving fluid into the first conduit, where said first driving fluid is in contact with the reducing agent, at least a fraction of which is then oxidized to an oxidizing agent, and
• a first separation device connected to the first outlet and arranged to separate the first driving fluid, depleted in dioxygen, from the liquid and to return the separated liquid to the tank, and
• a reduction loop comprising:
• a second conduit comprising a second inlet opening into the tank, arranged to take in a second part of the liquid comprising at least the oxidizing agent, and a second outlet, and
• a second injection device connected to a supply of a second driving fluid comprising a fuel comprising carbon, and arranged to introduce the second driving fluid into the second conduit, where said second driving fluid is in contact with the oxidizing agent, at least a fraction of which is then reduced to a reducing agent, and
• a second separation device connected to the second outlet and arranged to separate the second driving fluid, enriched with carbon dioxide, from the liquid and to return the separated liquid to the tank.
