Abstract (en)
A sulfur-containing heavy liquid hydrocarbonaceous fuel and/or solid carbonaceous fuel with a nickel, vanadium, and silicon containing ash is mixed with a copper and/or cobalt-containing material, or a silicon-containing material, and a copper and/or cobalt-containing material. The mixture is reacted by partial oxidation in a down-flowing free-flow unobstructed vertical reaction zone with refractory lined walls at a temperature in the range of about 1800 DEG F to 2900 DEG F. A raw effluent gas stream is produced comprising H2+CO and containing entrained slag comprising the following phases: (i) an alloy phase selected from the group consisting of Cu-Ni Co-Ni Cu-Fe, and mixtures thereof; (ii) a silicate phase selected from the group consisting of copper silicate, cobalt silicate, and mixtures thereof; (iii) a spinel phase; and (iv) a fluid oxysulfide phase comprising at least one sulfide from the group consisting of Cu, Co, Fe, and mixtures thereof. There is a reduction in the mole ratio H2S + COS/H2 + CO in the raw effluent gas stream. Non-gaseous materials e.g. slag containing substantially no Ni3S2 are separated from the hot raw effluent gas stream from the gasifier.
