A method for removing arsenic and/or phosphorus from a petroleum charge with a retaining material comprising: (a) from 60 to 97% of a carrier containing, by weight, from 1.5 to 60% of oxide of at least one metal A selected from the group consisting of Mg, Ca, Sr, Ba, Mn, Fe, Co, Ni, Cu and Zn, disso
A method for removing arsenic and/or phosphorus from a petroleum charge with a retaining material comprising: (a) from 60 to 97% of a carrier containing, by weight, from 1.5 to 60% of oxide of at least one metal A selected from the group consisting 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, with which the carrier is impregnated by exchange or depositing, and (c) possibly from 0 to 1% of platinum and/or palladium oxide with which the carrier is impregnated.

A method of removing at least one of arsenic and phosphorus from an at least partially liquid hydrocarbon charge, comprising contacting said charge, molecular hydrogen and a retaining material in a reaction zone, at a temperature of 100°to 250°C. and a pressure of 1 to 100 bars, with an hourly throu
A method of removing at least one of arsenic and phosphorus from an at least partially liquid hydrocarbon charge, comprising contacting said charge, molecular hydrogen and a retaining material in a reaction zone, at a temperature of 100°to 250°C. and a pressure of 1 to 100 bars, with an hourly throughput volume (LHSV) relative to the volume of retaining material, of from 1 to 20 h-1 and with an hourly throughput of hydrogen of 0.5 to 10 liters per liter of charge, said retaining material comprising by weight: (a) from 60 to 97% of a carrier containing, by weight, from 1.5 to 60% of oxide of at least one metal A selected from the group consisting 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, distributed in pores of said carrier, said retaining material, prior to said contacting, having been subjected to a reducing stage in the presence of molecular hydrogen or a gas containing molecular hydrogen, at a temperature of 100°to 500°C.
