Due to the high compressive strength and good thermal ability, the hot-pressed coal briquette prepared with the HyperCoal is considered to be an excellent alternative fuel for the lump coal in the COREX. In this paper, state changes of GD-coal and KL-HyperCoal during the heating process were observed in situ through an ultra-high temperature laser confocal microscope. Compared with GD-coal, KL-HyperCoal has an excellent thermoplasticity, which contributes to the preparation of the hot-pressed coal briquettes with high mechanical strength. The Raman spectra and infrared spectra analysis were used to investigate the material structure of the hot-pressed coal briquettes. It is proved that increasing the hot-pressing temperature can improve the compressive strength, while extending the holding time period can hardly change the compressive strength. The above results indicate that HyperCoal can be used as a binder to effectively improve the performance of the hot-pressed coal briquettes.
