COMPTES RENDUS DE L ACADEMIE DES SCIENCES SERIE II FASCICULE C-CHIMIE
The RAM II process developed by the 'Institut francais du petrole' is ideal
ly suited for simultaneous removal of arsenic, mercury and lead, if present
, from contaminated feedstocks upstream of aromatic complexes or steam-crac
king units. The wide nature of the mercury and arsenic compounds requires a
two-step process in which the organo-arsenic compounds are hydrogenolysed
and adsorbed in a catalytic step, where the organo mercuric species are dec
omposed into hydrocarbons and metallic mercury, the latter being subsequent
ly absorbed on a trapping mass in a second step. (C) 2000 Academie des scie
