摘要： This invention relates to a hydroprocessing process for the improvement of catalyst life. Such inventive process is carried out with intermittent or discontinuous addition of a co-feed stream when hydroprocessing petroleum based feedstock or an oxygen containing feedstock. More specifically, it has been found that intermittent or discontinuous addition of the co-feed stream such as carbon monoxide, carbon dioxide, or their precursors to the hydrogen stream can reduce the long term deactivation, extend the life and increase run length of a cobalt/molybdenum hydrotreating catalyst.
