摘要
This invention relates to an improved methodology for the removal of oily hydrocarbon materials sorbed onto the surface(s) of inorganic materials. Said oily hydrocarbon materials may be partially oxidized or may be unoxidized. The invention makes use of an exothermic chemical reaction involving hydrogen peroxide and alkaline agents and hydrocarbons to partially oxidize certain reactive functional groups on the hydrocarbons and thus rendering said hydrocarbons more water soluble thereby facilitating the separation of the sorbed or free product hydrocarbons from both the surface of the inorganic material and also from between the interstitial grains (porosity). Furthermore the exothermic process facilitates the reduction of viscosity of said hydrocarbons thus further facilitating the separation of the hydrocarbons from the aqueous and inorganic phases. Said separation can be further enhanced by standard separation techniques such as settling, centrifugation, decantation, use of cyclones, and any and all other physical separation processes. Further by utilizing the hydrogen peroxide in an alkaline environment the interfacial tension of the oil is reduced further aiding said hydrocarbon-water-inorganic sediment separation and recovery of the hydrocarbons.
