Abstract: Flue gas resulting from combustion of sulfur-containing fuel is treated for reduction of its sulfur dioxide content by creating in it a suspension of finely divided sorbent such as lime, and then contacting it at elevated temperature in a vertical contacting zone with a descending shower of sulfur dioxide oxidation catalyst. The resulting sulfur trioxide is captured as a powdered sulfate.

Abstract: A method of fuel treatment and distribution for an automobile internal combustion engine comprising the steps as follows:(a) vaporizing liquid alcohol to form alcohol vapor;(b) providing a substantial amount of engine exhaust heat to an endothermic reactor having an endothermic dissociation catalyst therein,(c) contacting said vapor and said endothermic dissociation catalyst for form a hydrogen-rich gaseous-vapor mixture,(d) mixing said hydrogen-rich gaseous-vapor mixture with air to form a partial combustion mixture,(e) operating an adiabatic reactor without a substantial amount of exhaust heat within an operational temperature range, said adiabatic reactor having a catalyst bed comprising a partial combustion catalyst and a dissociation catalyst,(f) contacting said partial combustion mixture and said partial combustion catalyst and said dissociation catalyst whereby a fuel mixture is formed.

Abstract: A method of fuel treatment and distribution for an internal combustion engine including the steps as follows:(a) operating an adiabatic reactor without a substantial amount of exhaust heat within an operational temperature range, the catalyst bed reactor including a partial combustion catalyst and a dissociation catalyst;(b) providing a substantial amount of engine exhaust heat to an endothermic reactor having an endothermic dissociation catalyst therein,(c) vaporizing liquid alcohol to form alcohol vapor;(d) mixing the alcohol vapor with air to form a partial combustion mixture;(e) contacting the partial combustion mixture and the partial combustion catalyst whereby a dissociation mixture is formed and heat is evolved;(f) contacting the dissociation mixture and the dissociation catalyst to form a hydrogen rich fuel;(g) contacting the hydrogen-rich fuel and the endothermic dissociation catalyst to form a fuel product whereby at least a portion of any residual undissociated alcohol in the hydrogen-rich fuel is
