摘要： A particulate selective hydrogenation catalyst for hydrogenating unsaturated diolefinic hydrocarbons to &agr;-olefinic hydrocarbons at rates which are at least 1.5 times higher than the rate of hydrogenation of &agr;-olefinic hydrocarbons to saturated compounds contains palladium distributed at the periphery of particles (spherules or extrudates), and at least one element selected from tin and lead. Further, the tin and/or lead is advantageously distributed at the periphery of the spherules or extrudates.

摘要： A catalyst for hydrogenating aromatic compounds contained in feeds containing sulfur-containing compounds comprises platinum, palladium, fluorine and chlorine, on a support principally comprising alumina. This catalyst is of particular application to hydrogenating aromatic compounds with boiling points of more than 100° C. in hydrocarbon-containing feeds containing sulfur-containing compounds.

摘要： The invention concerns the preparation of a catalyst comprising a support containing at least one oxide of the element Si, Al, Ti, Zr, Sn, Zn, Mg or Ln (where Ln is a rare earth), cobalt, at least one element A selected from the group formed by ruthenium, platinum, palladium and uranium, and at least one element B selected from the group formed by molybdenum and tungsten, characterized in that it comprises at least the following successive steps: (1) formation of a precursor comprising at least cobalt and at least a portion of the support; (2) at least partial reduction of the precursor in the presence of at least one reducing compound; and (3) deposition of any part of compound present in the catalyst and not present in the precursor on the reduced precursor. The invention also concerns the use of the catalyst in a process for the synthesis of C.sub.5.sup.+ hydrocarbons from synthesis gas.
