Hot Coke Strength in CO2 Reaction [PDF]
Hot Coke Strength in CO2 Reaction, 2022 This study aims to investigate the strength of coke at high temperature in reaction atmosphere. A uniaxial compression test measured the fracture stress of coke at three conditions: (i) room temperature and air atmosphere; (ii) 1100°C and N2 atmosphere; (iii) 1100°C and CO2 atmosphere.
