Abstract
Official abstract text for this publication.
The invention concerns a thioresistant catalyst which comprises an active phase deposited on a support, said active phase comprising at least one noble metal from group VIIIB and at least one metallic oxide from group IB or from group IIB, said support being selected from the group formed by refractory oxides, coal, clays, silica-alumina and/or their mixtures, and said support having a specific surface area in the range 110 to 300 m 2 /g. The invention also concerns the process for the preparation of said catalysts and their uses in the selective hydrogenation of hydrocarbons comprising acetylenic, dienic and/or alkenylaromatic functions. The invention is applicable to the refining field, and more particularly to the treatment of gasolines obtained by steam cracking (pyrolysis gasoline).
First claim
Opening claim text (preview).
The invention claimed is: 1. A thioresistant catalyst comprising an active phase deposited on a support, said active phase consisting of at least one noble metal from group VIIIB in the reduced form, which is selected from the group consisting of platinum and palladium and at least 2% to 50% by weight of a metallic oxide from group IB or from group IIB with respect to the total catalyst weight, said metallic oxide being selected from the group consisting of copper oxide, zinc oxid…
