Hot Strength of Coke Prepared by Briquetting and Carbonization of Lignite

The hot strength of coke prepared from an acid-washed lignite by briquetting-carbonization before and after CO2 gasification was, for the first time, investigated in this work. at 1000°C was higher than measured a room temperature. resulted linear decrease with reaction time. lignite-coke showed faster during gasification, compared to conventional cokes derived caking coal or non-or slightly coal, due high reactivity caused its porous structure catalytic metal species remaining even acid-washing, while it superior initial stage gasification.
