Abstract

Abstract A solids dispersant comprising an oil-soluble salt is added to catalytic slurry of hydrocarbonaceous charge stock to reduce coke deposits in conversion at temperatures above about 400° F. Dosage is about 0.0001% to 1% of a condensation product of an epihalohydrin and equimolar amount of C 12 -C 40 alkylamine.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 186 words
In a process for the conversion of an asphaltene-containing hydrocarbonaceous charge stock which comprises the steps of: (a) forming a reactive slurry of said charge stock, hydrogen and a finely divided catalyst containing at least one metal component from the metals of Groups V-B, VI-B and VIII of the Periodic Table; (b) reacting said slurry at hydrocarbon conversion conditions including a pressure above about 100 psig and a temperature above about 400° F.; and, (c) recovering a hydrocarbonaceous product; the improved method of reducing the formation of coke and other undesirable deposits in the process, which comprises effecting said reaction of the slurry in admixture with from about 0.0001% to about 1% by weight, based on the hydrocarbonaceous charge stock, of a solids dispersant comprising an oil-soluble HCl salt of the condensation product, formed at a temperature of from about 20° C. to about 150° C., of equimolar amounts of an epihalohydrin compound and an alkyl amine having from about 12 to about 40 carbon atoms per molecule, from about 1% to about 20% of the amino nitrogen in said condensation product being neutralized with HC1.
Claim 2
