Possibility and Process of the Use of Upgraded Coal and Coke from Indonesian Lignite Coal in the Iron Making Process

This study explored the possibility of using upgraded coal and coke from Indonesian lignite in ironmaking process, specifically pulverized Injection (hereafter, “PCI”) carbon composite pellets material (sintering binder material). The found that (1) injection into blast furnace will have same effect as lime - heavy oil slurry furnace, combined infusion highly volatile matter low ash coal, flash pyrolysis.
