摘要
The present invention concerns a process for pretreating a catalyst used in hydrocarbon conversion processes, comprising the following steps:a) pretreating a catalyst containing at least one zeolite with structure type EUO and at least one hydrodehydrogenating metal in the presence of a hydrocarbon feed, at a temperature such that a catalyst comprising carbon is obtained;b) then treating the hydrocarbon feed and the catalyst at a temperature which is lower than the temperature applied in step a).The invention also concerns an activated catalyst and its use in a process for isomerizing aromatic compounds containing 8 carbon atoms.
