The adsorption of oxygen on degassed brown coal char has been investigated gravimetrically in the temperature range 25"-200ยฐC and at pressures up to 1 atm. The adsorption occurs by two separate processes, one reversible and the other irreversible. Methods have been devised to investigate these proce
Combustion rate measurements of Loy Yang brown coal char particles (88 #m median size) over the temperature range 940-1420 K yielded a chemical rate coefficient Re, expressed as Re= 12.6 expl-68.3/(RTp)] kg/m2s (kPa 02) ยฐ.4. Particle size and density decreased with burn off, but in an unusual manne
