Najjar, M S

A process is described for the production of gaseous mixtures comprising H/sub 2/ + CO by the partial oxidation of a feedstock consisting of a heavy liquid hydrocarbonaceous fuel having a nickel and vanadium-containing ash or petroleum coke having a nickel and vanadium-containing ash, or mixtures thereof. The feedstock includes a minimum of 0.5 wt% of sulfur. The ash includes a minimum of 5.0 wt% vanadium, a minimum of 2.0 wt% of nickel and less than about 350 parts per million of silicon. The process comprises: mixing together an iron-containing additive consisting of at least one iron compound with the feedstock; wherein the weight ratio of iron-containing additive to ash in the reaction zone is in the range of 1.0-10.0 to 1.0, and there is at least 10 parts by weight of iron for each part by weight of vanadium.
