Abstract
The average intrinsic reactivities for the three chars, during reaction in 10 vol.% oxygen at 500 °C and atmospheric pressure, were found to be 0.46×10-6,0.21×10-6 and 1.36×10-6gm-2s-1, respectively, for the wood-chip, newspaper and glossy-paper chars and the corresponding peak reactivities were 1.43×10-6,1.06×10-6and 5.80×10-6gm-2s-1. The reactivities for the chars differ as a function of conversion and ash content, but no trend in terms of either increasing or decreasing reactivity with increasing ash content was found. Moderate heat treatment, where the char is exposed to 1277 °C for 47 ms, had no significant influence on char reactivity.
