Latest Patents
One of his latest patents is titled "Desulfurizing of reducing gas stream using a recycle calcium oxide system." This innovative process involves producing a low-sulfur content hot reducing gas stream by contacting a sulfur-bearing hot reducing gas stream with a desulfurizing agent. The agent comprises a fixed bed of solid particles made of calcium oxide, which results in a low-sulfur content gas and a calcium sulfide composition. The process further includes regenerating the calcium oxide and avoiding the formation of calcium sulfate during regeneration.
Another notable patent is the "Process for the passivation of sponge iron utilizing reducing gases." This method allows for the passivation of sponge iron through mild reoxidation by exposing it to a specific gaseous atmosphere at controlled temperatures. The process is particularly beneficial for in-line passivation of hot reduced pellets within a shaft furnace.
