| abstract |
The present invention relates to a process for upgrading heavy hydrocarbon feedstocks in one or more hydrogenation conversion reactors for the hydrogenation of heavy hydrocarbon feedstocks and for the hydrogenation treatment of heavy hydrocarbon feedstocks in at least one hydrotreating reactor Wherein the method comprises the preparation of two or more catalysts, wherein each catalyst is prepared from at least one catalyst precursor in one or more specific production reactors, said catalyst precursor being selected from the group consisting of IIA, IIIB, IVB, VB, VIB , VIIB, VIII, IB, or IIB, wherein each of the production reactors is fed to at least one hydrogenation conversion or hydrogenation treatment reactor, and wherein each catalyst contained in the production reactor is fed to the feedstock To a hydrogenation treatment or a hydrogenation treatment. This method allows the production of products of good quality under continuous operating conditions. |
