Hydroconversion process for heavy hydrocarbonaceous feedstock

摘要

The invention concerns a process for hydroconversion of a hydrocarbonaceous feedstock comprising:
- a preparation step of at least one catalyst in one or more preparation reactor upstream from a reaction section, wherein
- (i) at least one preparation reactor feeds one or more reactor of the reaction section, or
- (ii) preparation reactors are dedicated for catalysts fed to at least a hydroconversion reactor or at least a hydrotreatment reactor of the reaction section;
- a separation step of solids contained in the liquid effluents issued from the reaction section,
- a treatment step of residues issued from separation section, comprising a partial oxidation step wherein said residues are partially oxidized to produce carbon monoxide, hydrogen an a metal containing residue. Such process permits improving of products quality, operation of the separation section, recovering of catalytic metals contained in the feed and supplying hydrogen to the reaction section.
