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 (), upstream from combustion zone (), through atomization means () 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 (), the operating conditions in transport zone () 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 () to a combustion zone () allowing reduction of the metal oxide particles, said combustion zone () comprising at least one dense-phase fluidized bed. The invention can be advantageously applied to COcapture and energy production.

The invention relates to a method for upgrading heavy liquid fractions resulting from oil refining, by combustion in a fluidized-bed chemical looping process. The method according to the invention allows energy to be produced by oxidizing totally the heavy liquid feeds while allowing direct capture of the COemitted in the combustion fumes. The method according to the invention also allows a synthesis gas to be produced.

The invention relates to a process for synthesising hydrocarbons starting from a feedstock containing synthesis gas. In the process a solid Fischer-Tropsch catalyst is employed in a three-phase reaction section operated so that the catalyst is maintained in suspension in a liquid phase by the circulation of a gaseous phase from the bottom to the top of the reaction section. The process utilizes conditions to control and maintain the homogeneity of the concentration of catalyst particles in the reaction section.

The present invention describes a thin layer fixed bed reactor intended for chemical treatments, in particular reduction of a Fischer-Tropsch synthesis catalyst. The reactor is designed in the form of similar, compact modules and operates with a ratio of linear pressure drop to outlet pressure which falls within certain limits.
