Abstract:
1. A process for hydrogenation of benzene contained in a catalytic reformate comprising the steps of: separating, in a separator tank, hydrogen present in the catalytic reformate from the remainder of the reformate, said separating being conducted at a medium pressure ranging from 10 to 20 bar, separating resultant hydrogen-depleted reformate into a benzene-enriched light reformate fraction and a heavy reformate fraction, hydrogenating the benzene-enriched light reformate fraction through contact with a nickel-based hydrogenation catalyst comprising 10-60% by weight of nickel, having an active surface whose dispersion is at least 10% at a pressure ranging from 10 to 20 bar, at a temperature of between 90° C. and 150° C., a VVH of between 0.5 and 10, and with at least one portion of hydrogen obtained from said separator tank at said pressure of 10 to 20 bar without recompression of said hydrogen, so as to provide a hydrogenated product stream.
