Macrostrength And Pore Structure Of Coke Subjected To Gasification And Annealing Under Blast Furnace Conditions, Xing Xing, Harold P. Rogers, Guangqing Zhang, Paul Zulli, Oleg Ostrovski

Faculty of Engineering and Information Sciences - Papers: Part A

Metallurgical cokes were subjected to gasification by CO-CO2-N2 gas with blast furnace-like composition-temperature profile to 1400 °C and annealing under N2 at temperature up to 2000 °C. The degradation of coke strength following reaction and annealing was characterised using tensile testing. Both gasification and annealing decreased the mechanical strength of coke. Degradation of all examined cokes by gasification at 1400 °C was stronger in comparison with annealing at the same temperature.
