SPHERICAL-SHAPED DOPE-SUPPORTING CATALYST AND HYDROTREATING AND HYDROCONVERSION PROCESS OF PETROLEUM FRACTIONS CONTAINING METALS

摘要

the present invention relates to a catalyst for hydrotreating and / or hydroconversion heavy metal containing hydrocarbon charge.the catalyst includes a support in the form of logs based on alumina.at least one metal catalyst or a catalytic metal compound of group vib (column 6 of the periodic table of the elements of the score).the catalytic metal may be at least a catalytic metal compound and a group viii (columns 8, 9 and 10 of the periodic table of the elements of the score).the porous structure comprises a plurality of agglomerates formed side by side, each of a plurality of acicular platelets.the platelets are oriented generally radially of the assembly towards each other and to the center of the cluster.the catalyst also contains at least one element selected from the group formed by doping boron, phosphorusthe silicon (or silicon, which does not belong to that which might be contained in the chosen support) and halogens.the invention also relates to the use of said catalyst for the conversion of metal loads.
