MUMBAI, India, Aug. 1 -- Intellectual Property India has published a patent application (202431005218 A) filed by Jindal Steel & Power Limited, Angul, Orissa, on Jan. 25, 2024, for 'a method for performing a gas based direct reduction of iron using nut coke.'
Inventor(s) include Damodar Mittal; Jayanta Kumar Kundoo; Poliki Srinivasa Reddy; Rajendra Kumar Makkad; Ajay Kumar Bisen; and Madhumita Kumari.
The application for the patent was published on Aug. 1, under issue no. 31/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method (300) for performing a gas based direct reduction of iron using nut coke. The method (300) enhances gas-based direct reduction of iron using nut coke by feeding a predetermined quantity of nut coke (302) into a feeding system of a Direct Reduced Iron (DRI) plant by a transfer system (114), where it is stored in a nutcoke surge bin (104) and feeding a predetermined quantity of iron ore pellet (304) into the feeding system where it is stored in a pellet surge bin (108). The nut coke is then mixed with iron ore pellets (306) in the reduction furnace (110) forming a first mixture to generate reducing gases, primarily CO and H2, which reduce iron oxide (Fe2O3) to metallic iron (Fe). The method(300) further includes adjusting the nut coke feed rate based on production capacity, ensuring optimal resource utilization and consistent DRI quality."
