CA 2224690

The present invention relates to a catalyst for use in a process for the preparation of hydrocarbons comprising cobalt and manganese and/or vanadium, supported on a carrier, wherein the cobalt: (manganese + vanadium) atomic ratio is at least 12:1. Preferably, the cobalt: (manganese + vanadium) atomic ratio is at most 1500:1. The invention further relates to a process for the preparation of hydrocarbons which comprises contacting a mixture of hydrogen and carbon monoxide at elevated temperature and pressure with a catalyst as described hereinbefore. Typically, at least part of the cobalt is present in the metallic state.

La présente invention se rapporte à un catalyseur utilisé dans un procédé pour la préparation d'hydrocarbures comportant du cobalt et du manganèse et/ou du vanadium, portés par un support, dans lequel le rapport atomique cobalt: (manganèse + vanadium) est d'au moins 12:1. De préférence, le rapport atomique cobalt: (manganèse + vanadium) est tout au plus égal à 1500:1. En outre, l'invention se rapporte à un procédé de préparation d'hydrocarbures consistant à mettre en contact un mélange d'hydrogène et de monoxyde de carbone à température et pression élevées avec un catalyseur tel que décrit précédemment. Typiquement, une partie au moins du cobalt est présent à l'état métallique.
