The invention pertains to a process and catalyst for removing arsenic and one or more other metal compounds, e.g. silicon, vanadium and nickel, from a hydrocarbon feedstock. The catalyst comprises a molybdenum compound and a nickel compound on a carrier. The catalyst has a surface area of at least 200 m2/g. Next to contaminant removal, the catalyst is also suitable for hydrodesulphurisation, hydrodenitrogenation and/or hydrygenation.
L'invention a trait à un procédé et à un catalyseur permettant d'éliminer l'arsenic et un ou plusieurs autres composés métalliques, tels que le silicium, le vanadium et le nickel, d'une charge d'hydrocarbures. Le catalyseur selon l'invention comprend un composé de molybdène et un composé de nickel sur un support. Le catalyseur possède une surface active d'au moins 200 m?2¿/g. En plus de son action d'élimination d'impuretés, le catalyseur selon l'invention convient à l'hydrodésulfuration, l'hydrodénitrogénation et/ou l'hydrogénation.
