Abstract: The process produces a stream of hot clean gas substantially free from particulate matter, ammonia, alkali metal compounds, halides and sulfur-containing gas for use as synthesis gas, reducing gas, or fuel gas. A solid carbonaceous fuel with or without liquid or gaseous hydrocarbonaceous fuel and containing halides, alkali metal compounds, sulfur, nitrogen and inorganic ash, is reacted by partial oxidation to produce a hot raw gas stream comprising H2, CO, CO2, H2O, CH4, NH3, HCl, HF, H2S, COS, N2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream is split into two streams which are separately deslagged, cleaned and recombined. Ammonia in the gas mixture is catalytically disproportionated into N2 and H2. The ammonia-free gas stream is then cooled and halides in the gas stream are reacted with a supplementary alkali metal compound to remove HCl and HF. Alkali metal halides, 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 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 540 DEG C.

Abstract: The process produces 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 fuel selected from liquid hydrocarbonaceous fuel or liquid emulsions thereof, an aqueous slurry of petroleum coke, and mixtures thereof and containing halides, alkali metal compounds, sulfur, nitrogen and inorganic ash, it reacted by partial oxidation to produce a hot raw gas stream comprising H2, CO, CO2, H2O, CH4, NH3, HCN, HC1, HF, H2S, COS, N2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream is cooled and cleaned. Optionally, ammonia is removed 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 HC1, HF and HCN. Alkali metal halides and alkali metal cyanide, vaporized alkali metal compounds and residual fine particulate matter are removed by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a 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 540 DEG C.
