Nickel-based adsorbens for arsenic and phosphor removal from liquid hydrocarbon fractions, its preparation and its use

摘要

A trapping mass for removing arsenic and/or phosphorus from a petroleum feedstock and a process for its preparation are described. This mass comprises: a) from 60 to 97% of a support containing, by weight, from 1.5 to 60% of oxide of at least one metal A chosen from the group made up of Mg, Ca, Sr, Ba, Mn, Fe, Co, Ni, Cu and Zn, dissolved in alumina in the form of aluminate, and from 40 to 98.5% of at least one alumina, b) from 3 to 40% of nickel oxide impregnated by exchange or by deposition onto the support and c) optionally from 0 to 1% of palladium and/or platinum oxide impregnated onto this support.
