摘要：

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) 1 100 degrees C and N-2 atmosphere; (iii) 1 100 degrees C and CO2 atmosphere. The drum index (DI) and coke strength after reaction (CSR) were also measured. The DI and CSR of coke produced by a lump of caking coal were higher than those of coke produced by non- or slightly caking coal. The compression tests showed that the fractured stress at room temperature in the air atmosphere was lower than that at 1 100 degrees C in the N-2 atmosphere. Also, the fractured stress at 1 100 degrees C in the N-2 atmosphere was higher than that at 1 100 degrees C due to the CO2 reaction. The DI, CSR, and hot coke strength of coke produced by caking coal was higher than those of coke produced by non- or slightly caking coal.
