A partial oxidation process for the production of a stream of hot clean gas substantially free from particulate matter, alkali metal compounds, hydrogen halides, hydrogen cyanide, sulfur-containing gases, and with or without ammonia for use as synthesis gas, reducing gas, or fuel gas. A pumpable hydrocarbonaceous fuel selected from the group consisting of liquid hydrocarbonaceous fuel or liquid emulsions thereof, an aqueous slurry of petroleum coke, and mixtures thereof and wherein said hydrocarbonaceous fuel contains halides, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, is reacted in a gasifier by partial oxidation to produce a hot raw gas stream comprising H2, CO, CO2, H2O, CH4, NH3, HCN, HCl, HF, H2S, COS, N2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream from the gasifier is cooled in a radiant cooler and cleaned. Optionally, ammonia is removed from the gas stream by being catalytically disproportionated into N2 and H2. The process gas stream is cooled and halides and HCN in the gas stream are reacted with a supplementary alkali metal compound to remove HCl, HF and HCN. Alkali metal halides and alkali metal cyanide, vaporized alkali metal compounds and residual fine particulate matter are removed from the gas stream by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a regenerable sulfur-reactive mixed metal oxide sulfur sorbent material to produce a sulfided sorbent material which is then separated from the hot clean purified gas stream having a temperature of at least 1000°F.

A partial oxidation process for producing hot, clean synthesis gas, reducing gas, or fuel gas substantially free from particulate matter, hydrogen halides, hydrogen cyanide, alkali metal compounds, and sulfur-containing gases, comprising: (1) reacting a pumpable hydrocarbonaceous fuel feedstock by partial oxidation with a free-oxygen containing gas wherein said hydrocarbonaceous fuel feedstock comprises a fuel selected from the group consisting of liquid hydrocarbonaceous fuel or liquid emulsions thereof, an aqueous slurry of petroleum coke, and mixtures thereof, and wherein said fuel contains halide, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, and said fuel is reacted with a free-oxygen containing gas in a free-flow vertical refractory lined partial oxidation gas generator to produce a hot raw gas stream having a temperature in the range of about 1800°F. to 3000°F. and comprising H2, CO, CO2, H2O, CH4, NH3, HCN, HCl, HF, H2S, COS, N2, Ar and containing particulate matter, and vapor phase alkali metal compounds; (2) partially cooling the hot raw gas stream from (1) to a temperature in the range of about 1000°F. to 1300°F. in a gas cooling zone; (3) separating out entrained particulate matter from the raw gas stream from (2); (4) introducing a supplementary alkali metal compound into the gas stream from (3) to react with the gaseous hydrogen halides and hydrogen cyanide present in the gas stream; cooling the resulting gas stream to a temperature in the range of about 800°F. to 1000°F. and filtering the gas stream and separating therefrom alkali metal halides and cyanide, any remaining alkali metal compounds, and any remaining particulate matter; and (5) contacting the gas stream from (4) with a sulfur reactive oxide containing mixed metal oxide sorbent comprising a sulfur reactive oxide portion and a sulfur non-reactive oxide portion in a sulfur-removal zone, wherein the sulfur-containing gases in the gas steam from (4) react with said sulfur reactive oxide containing mixed metal oxide sorbent to produce a sulfided sorbent material; and separating said sulfided sorbent material from the gas stream to produce a clean gas stream substantially free from particulate matter, alkali metal compounds, hydrogen halides, HCN, H2S, and COS, and having a temperature of at least 1000°F.
