| 摘要 |
The invention relates to a method for the selective hydrogenation of a feedstock of polyunsaturated hydrocarbons containing at least two carbon atoms per molecule and having a final boiling point of no higher than 250°C, said method consisting of contacting said feedstock with a catalyst, the active phase of which includes at least one Group VIII metal deposited on a substrate consisting of at least one oxide, said catalyst being prepared according to a method including: i) at least one step of contacting at least said substrate with at least one solution containing at least one precursor of at least said Group VIII metal, ii) at least one step of contacting at least said substrate with at least one organic compound comprising at least one cyclic oligosaccharide consisting of at least six glucopyranose subunits bonded at α-(1,4); and iii) at least one calcination step for obtaining at least said Group VIII metal in oxide form, wherein steps i) and ii) can be carried out separately in any order, or simultaneously. |
