Abstract
In this report, the writer go further than the view point of 2nd report, and has made clear the relation between wettability of coal and oxygen functional group in coal.(See Fig. 3-10.)He has concluded as follows;In the case of bituminous coals, their wettabilities have no correlation with their oxygen functional groups without hydroxyl groups.On the other hand, in the case of brown coals, their wettabilities have correlation with their oxygen functional groups.(Concerning carboxyl groups, healready mentioned this point in the 2nd report.)On above-mentioned point of view, he has added the information from model materials of Table 2.(There are more model materials than ones in the 2nd report.)Besides, he has submitted the reformative result of the pyrolysis reaction which remove oxygen functional group in low-rank coal by autoclave.(See Table 3-4, and Fig. 12-14.)
