METHOD OF EXTRACTING VANADIUM FROM PETROLEUM COKE

摘要

FIELD: oil and gas industry.;SUBSTANCE: invention relates to process for production of vanadium from petroleum coke by leaching. Method includes crushing petroleum coke and then leaching vanadium therefrom with a mixture of concentrated sulfuric and nitric acids. Degree of vanadium extraction is 72.19–80.85 %, while the weight of the dry residue of petroleum coke is 92.6–96.1 %, which makes it possible later to use the latter as a carbon reducing agent in metallurgy, as an absorbent in chemical production.;EFFECT: method of extracting vanadium from petroleum coke will find wide application in refineries with processes of delayed coking of petroleum raw materials.;1 cl, 1 tbl, 5 ex
