PROCESS FOR CONVERTING HEAVY PETROLEUM FRACTIONS THAT COMPRISE A DISTILLATION STAGE EBULLATED-BED HYDROCONVERSION STAGES OF THE VACUUM DISTILLATE AND A VACUUM RESIDUE AND A CATALYTIC CRACKING STAGE

摘要

The present invention relates to a process for converting a hydrocarbon fraction derived from atmospheric distillation of crude oil. (B) treating at least a portion of the vacuum distillate in the presence of hydrogen; (c) heating the vacuum distillate to a vacuum distillate Treating at least a portion of the vacuum residue in the presence of hydrogen, wherein said steps (b) and (c) each operate in a liquid-gas upflow mode and comprise at least one boiling-(D) feeding at least a portion of the product from step (b) to an atmospheric distillation zone to recover the light and heavy liquid fraction from the atmospheric distillation zone; (e) Feeding at least a portion of the product obtaiin step (c) to an atmospheric distillation zone, recovering the light and heavy liquid fraction from the atmospheric distillation zone, and optionally (f) And a catalytic cracking step of decomposing at least a portion of the heavy liquid fraction obtaiin steps (d) and (e) at least partially into a hard fraction of the fuel type.
