Abstract: The present invention relates to a device and a method for chemical looping combustion, for which the end of the intake duct (4) opening out within the chamber of the separator (1) is inclined with respect to a horizontal plane (H).

Abstract: The invention relates to a CLC plant for the combustion of solid hydrocarbon feedstocks generating particles of unburnt residues, comprising a solid/solid separator above the combustion reactor in order to efficiently separate the particles of the oxygen-carrying solid from the particles of unburnt residues contained in the gas/solid mixture (14) exiting from the combustion reactor. The chamber (1) of the solid/solid separator, the combustion reactor and the inlet (2) for the gas/solid mixture (14) of the chamber have a parallelepiped shape. The inlet (2) is equipped at its top with means (3) for distribution of said gas/solid mixture in the chamber which extend over the entire length of the inlet, improving the solid/solid separation.

Abstract: An improved process is provided for catalytic pyrolysis of biomass, comprising pneumatically injecting a biomass feed via a pneumatic injection line into a fluidized heat medium, for example, hot catalyst, with a carrier gas at a velocity of from 5 to 40 m/s in at least one mixing zone in communication with a pyrolysis reactor in which catalytic pyrolysis occurs, and maintaining a catalyst/biomass mixture flowrate ratio (C/B) of from 4 to 40 downstream from the point of catalyst injection via a catalyst injection line in the at least one mixing zone.

Abstract: The present invention concerns a combustion reactor (300) for chemical looping combustion (CLC) configured to operate in a fluidised bed, comprising: a lower chamber (320) forming a first reaction zone for the combustion of a hydrocarbon feedstock in the presence of particles of an oxidation-reduction active mass, comprising a first side wall and being configured to include a dense fluidised bed; an elongate upper chamber (340) with smaller passage cross-section than that of the lower chamber, forming a second reaction zone for the combustion of gaseous effluents originating from the combustion in the lower portion, comprising a second side wall and being configured to include a dilute fluidised bed; an intermediate portion (330) connecting the two chambers, and including an inner wall forming a right angle with the side walls of the two chambers. The invention also relates to the facility and the CLC process incorporating such a reactor (300).
