Estimating the term…
The invention concerns a process for purification by elimination of chlorine in the form of hydrogen chloride and organochlorine compounds by contacting in the presence of hydrogen of at least a part of the effluent from a reforming, aromatics production, dehydrogenation, isomerisation or hydrogenation zone, said part of the effluent comprising olefins, hydrogen chloride and organochlorine compounds, on an elimination zone comprising a chain arrangement of two masses, the first mass being a mass comprising at least one metal from group VIII deposited on a mineral carrier and the second mass being a hydrogen chloride adsorbent.
A process for purification of at least a part of an effluent from a reforming zone said effluent comprising olefins, hydrogen chloride and organochlorine compounds by elimination of chlorine in the form of hydrogen chloride and organochlorine compounds, said process comprising contacting in the presence of hydrogen a part of the effluent in an elimination zone comprising a serial arrangement of two masses, the first mass being a mass comprising palladium impregnated on a mineral carrier and the second mass being a hydrogen chloride adsorbent, wherein said mineral carrier of said first mass consists of balls or cylindrical extrudates which consist of alumina and said palladium is present on said carrier at essentially only in a skin thickness of generally between 100 and 700 microns representing not more than 80% of the radius of said beads or extrudates.
