Estimating the term…
The quality of coke is improved by increasing the coking properties of a component of a coking feedstock (a coking additive) and by ensuring stability of the coking properties of a component when the coking additive constitutes up to 99% of the total volume of the coking feedstock. The result is an increase in the stability of a coking additive and in the coking properties of said coking additive. It is achieved by a petroleum coking additive consisting of a product of the delayed low temperature carbonization of heavy petroleum residues at temperatures of up to 500° C., said product being characterized by a 14 to 28% volatile substance content, the product of the delayed low temperature carbonization of heavy petroleum residues obtained at a recycle ratio of from 1.05 to 1.2 in the coking chamber is characterized by coking properties of not less than G on the Gray-King scale.
