Abstract: Facility for producing synthesis gas from a solid feedstock including organic matter, said facility including means for circulating a heat-carrying solid providing the heat necessary for such production, and several stages including gasification means (Z1, Z3), intermediate separation means (Z2, Z4) for separating the effluents coming from each stage, and combustion means (Z5).

Abstract: A process for conversion of a hydrocarbon feedstock comprising a relatively heavy main feedstock with a boiling point above approximately 350° C., and a relatively light secondary feedstock with a boiling point below approximately 320° C., wherein, the main feedstock, representing at least 50 wt. % of the hydrocarbon feedstock, is cracked in a fluidized-bed reactor in the presence of a cracking catalyst, the secondary feedstock is cracked in a fluidized bed with the same cracking catalyst, separately or mixed with the main feedstock, said secondary feedstock comprising oligomers with at least 8 carbon atoms of light olefins with 4 and/or 5 carbon atoms.

Abstract: The invention relates to a process for production of propylene in particular from a C4 and/or C5 cut from steam cracking and/or catalytic cracking, preferably comprising both butenes and pentenes, said process comprising at least one oligomerization stage, followed by a stage of catalytic cracking of the oligomers formed. Preliminary oligomerization, in particular of a wide fraction of the charge, makes it possible to optimize the yields, the conversion, and the selectivity for propylene, relative to direct cracking. It also makes it possible for cracking to be carried out in a fixed, moving, or fluidized bed, optionally with co-production of oligomers for uses other than the production of propylene.

Abstract: The invention relates to an installation and a process for the production of liquid fuels starting from a solid feedstock that contains the organic material in which: a) the solid feedstock is subjected to a gasification stage so as to convert said feedstock into synthesis gas, b) the synthesis gas is subjected to a purification treatment, c) the purified synthesis gas is subjected to a conversion stage that comprises the implementation of a Fischer-Tropsch-type synthesis so as to convert said synthesis gas into a liquid effluent and a gaseous effluent, d) the liquid effluent is fractionated so as to obtain a gaseous fraction, a naphtha fraction, a kerosene fraction and a gas oil fraction, and e) at least a portion of the naphtha fraction is recycled in gasification stage a).
