Example text

Variations in the extent of shrinkage brown coal per unit of moisture removed have been interpreted in terms of the role of different types of moisture in coal [1]. The isosteric heat of moisture sorption on coals has been observed to be a function of amount of water in the coal [10]. The fact that hysteresis in coal moisture sorption isotherms must be determined by shrinkage and swelling effects [11] complicates interpretation of such data, however. Perhaps one of the simplest illustrations of the multifaceted nature of water in coals has been provided by the observation that the dehydration behavior as a function of time is not particularly simple [12- 14].

INTRODUCTION The vitrinite macérais of bituminous coals are a group of aromatic-rich organic solids whose properties are often ranked against 'fundamental' parameters such as elemental carbon content and reflectance.

5% C. For these coals there is also a significant increase in AM2T(SO1V) during exposure to pyridine (but not the binary solvent) beyond - 7 0 days, indicating that déstabilisation by pyridine alone is a slow process. Although there is appreciable scatter in these plots of AM2j(solv) against carbon rank particularly in the case of the binary solvent, this parameter clearly approaches zero as elemental carbon content increases beyond 90%. This approach is more precipitous the greater the efficacy of the solvent treatment.
