Acidized carbon black process for acidized activation of carbon black for removal of polycyclic aromatic hydrocarbons from crude oil feed

Abstract

A process for removing polycyclic aromatic hydrocarbons from a crude oil feed is disclosed. The process for removing polycyclic aromatic hydrocarbons comprises contacting carbon black with an acidic solution to produce acidized carbon black. The acidic solution comprises water and one or both of nitric acid or phosphoric acid. The process additionally comprises contacting the acidic treated carbon black with nitrogen in an adsorption vessel and heating the adsorption vessel to 120 to 500° C., thereby producing activated carbon black. The process further comprises removing the polycyclic aromatic hydrocarbons from the crude oil feed by contacting the activated carbon black with the crude oil feed in the adsorption vessel.
