摘要
Pretreatment of a hydrocarbon feedstock containing arsenic and mercury before the hydrocarbon feedstock is subjected to a dearomatisation reaction. The invention is characterised in that the feedstock passes through an arsenic-trapping mass based on a support, on at least one metal from the group Ni, Co, Fe, Pd and Pt and on at least one metal from the group Cr, Mo, W and U and also passes through a mercury-trapping mass containing a support and a sulphide of a metal from the group Cu, Fe and Ag.
