Partial oxidation process
This patent describes a process for the production of gaseous mixtures comprising H/sub 2/ + CO by the partial oxidation of a feedstock; the process comprising: (1) mixing together an iron-containing additive with the feedstock; wherein the weight ratio of iron-containing additive to ash in the reaction zone in (2) is in the range of about 0.1-10.00 to 1.0, and there is at least 2 parts by weight of iron for each part by weight of vanadium; (2) reacting the mixture from (1) at a temperature in the range of 1700/sup 0/F to 3000/sup 0/F and a pressure in the range of about 5 to 250 atmospheres in a free-flow refractory lined partial oxidation reaction zone with a free-oxygen containing gas in the presence of a temperature moderator and in a reducing +Co and estrained molten slag, and wherein the reaction zone a atmosphere to produce a hot raw effluent gas stream comprising H/sub 2/ first portion of the iron-containing additive combines with at least a portion of the nickel, iron and sulfur constituents found in the feedstock to produce a first liquid phase washing agent; a second portion of the iron-containing additive combines with at least a portion of the silicon, aluminum, calcium, sodium and/or potassium, and iron constituents found in the feedstock to produce a second liquid phase washing agent; and wherein the first and second liquid phase washing agents collect and transport at least a portion of the vanadium-containing oxide laths and spinels and other ash components and refractory out of the reaction zone and (3) separating nongaseous materials from the hot raw effluent gas stream.
