Prevention of formation of nickel subsulfide in partial oxidation of heavy liquid and/or solid fuels
This patent describes a process for the production of gaseous mixtures comprising H/sub 2/ + CO by the partial oxidation of a fuel feedstock comprising sulfur-containing heavy liquid hydrocarbonaceous fuel and/or solid carbonaceous fuel, and the fuels having nickel, vanadium and silicon-containing ashes, and the feedstock includes a minimum of about 0.5 ppm nickel, a minimum of about 0.2 wt. % of sulfur, a minimum of about 1.0 ppm of vanadium, and a minimum of about 5.0 ppm of silicon. The process comprising: mixing together a copper and/or cobalt-containing material with the fuel feedstock; reacting the mixture by partial oxidation with a free-oxygen containing gas in a reducing atmosphere and in the presence of a temperature moderator at a pressure in the range of about 2 to 250 atmospheres in a down-flowing free-flow unobstructed vertical reaction zone with refractory lined walls of a partial oxidation gas generator; and separating non-gaseous materials containing substantially no Ni/sub 3/S/sub 2/ from the hot raw effluent gas stream.
