摘要

"Processes for the regeneration of catalysts of type catalyst of Raney type to the total or partial hydrogenation of nitrile functions into functions amine organic compounds.And for the hydrogenation of compounds, and to the semi hydrogenation of compounds ".The invention relates to a process for the regeneration of catalyst for hydrogenation and hydrogenation processes performed with a catalyst comprising at least one catalyst regenerated.More particularly,It refers to a process for the regeneration of catalysts used in the processes of Raney type total or partial hydrocarbon compounds comprising nitrile functions into amine functions.This process consists in the treatment of spent catalyst with a basic solution and optionally subjecting said catalyst to hydrogenation before washing to remove the impuritiesPresent on the catalyst. Thus, the regeneration process allows the recovery of up to 100% of the catalytic activity.
