Abstract
The invention relates to a device and to an improved method for chemical looping combustion of at least one liquid hydrocarbon feed, comprising: mixing the liquid feed with an atomization gas so as to feed it into a metal oxide particle transport zone (2), upstream from combustion zone (3), through atomization means (6) allowing to form finely dispersed liquid droplets in the atomization gas; vaporization of the liquid feed in form of droplets into contact with at least part of metal oxide particles in transport zone (2), the operating conditions in transport zone (2) being so selected that the superficial gas velocity after vaporization of the liquid feed is higher than the transport velocity of the metal oxide particles; sending all of the effluents from transport zone (2) to a combustion zone (3) allowing reduction of the metal oxide particles, said combustion zone (3) comprising at least one dense-phase fluidized bed. The invention can be advantageously applied to CO2 capture and energy production.
