Abstract
A method for making an oil soluble coking process additive, includes the steps of: providing mixture of a metal salt in water wherein the metal salt contains a metal selected from the group consisting of alkali metals, alkaline earth metals and mixtures thereof; providing a heavy hydrocarbon; forming an emulsion of the mixture and the heavy hydrocarbon; heating the emulsion so as to react the metal salt with components of the heavy hydrocarbon so as to provide a treated hydrocarbon containing oil soluble organometallic compound, wherein the organometallic compound includes the metal and is stable at a temperature of at least about 300° C. The oil soluble additive and a process using same are also disclosed.
