    摘要: A process for selective hydrogenation of unsaturated compounds such as acetylenic compounds or diolefins is carried out in the presence of a catalyst comprising at least one support, at least one metal from group VIII of the periodic table and at least one additional element M selected from the group formed by germanium, tin, lead, rhenium, gallium, indium, gold, silver and thallium. The process is characterized in that the catalyst is prepared using a process in which said metal M is introduced in an aqueous solvent, in the form of at least one organometallic compound comprising at least one carbon-M bond.

    摘要: A novel supported bimetallic catalyst comprises a group VIII metal such as platinum, and tin, at least a portion of which interacts strongly with the group VIII metal in the catalyst in the reduced state. In the partially oxidized state, the catalyst of the invention contains at least 10% of tin in the form of a reduced tin species with oxidation state 0, said species having an isomer shift in the range 0.80 to 2.60 mm/s and a quadrupolar splitting in the range 0.65 to 2.00 mm/s. The invention also concerns the preparation of said catalyst, and processes using said catalyst for transforming hydrocarbons into aromatic compounds, such as gasoline reforming processes and aromatic production processes.
