Urban, P; Stolfa, F

A method is described to prevent fouling of equipment used in high temperature coke producing petroleum reactions comprising the addition of an alcoholic aqueous mixture of an antifoulant comprising a phthalocyanine compound to a hydrocarbon feedstock at reaction conditions. The addition comprises the steps of: (a) sonicating a mixture of a phthalocyanine compound with water to form an aqueous dispersion of the phthalocyanine; (b) adding an alcohol to the aqueous dispersion to form an alcoholic aqueous dispersion of the phthalocyanine compound; and, (c) adding the alcoholic aqueous dispersion of the phthalocyanine compound to the hydrocarbon feedstock in an amount sufficient to reduce fouling of equipment employed during the high temperature coke producing petroleum reaction.
