  • Hydroconversion process for heavy hydrocarbonaceous feedstock
    Patent number: 9255229
    Abstract: 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.
    Type: Grant
