✦ Synopsis

calculated and discussed. The effects of gasification temperature over different periods on char-CO? gasification reactivity were not the snmc: the reaction was controlled by kinetics below II00 C and controlled by the diffusion at more than I100 C. The higher gasification temperature led to higher reactivity and low,er apparent activation energy. 97100061 Tribomechanical aspects of movement of coalcharge materials over a heated surface Parfenyuk, A.
