Process for removing vanadium and sulphur during the coking of a hydrocarbon feed

摘要

A process for producing metallurgical coke from a hydrocarbon residuum characterized by high vanadium and high sulphur contents comprises coking a hydrocarbon residuum in a coking drum in the presence of an additive selected from the group consisting of carbonates and hydroxides of sodium, potassium and calcium and mixtures thereof and an oxidizing agent selected from the group consisting of water, carbon dioxide and mixtures thereof.
