Swelling of hvB coal by vapour of the solvents pyridine, tetrahedrofuran, dimethylformamide and methanol was carried out. Vapour-saturated coals were extracted using selected solvents and extract yields for swollen and fresh coals were compared. It is found that some solvents can block pathways to s

Chloroform extraction for Yubari coal both raw and preheated at 300, 350 and 400ยฐC was carried out at various temperatures. The following results were obtained (1) 50 cm3 of chloroform per 1 g of sample is sufficient to extract almost completely, whatever the extraction tempetature, the chloroform-s
The relationship between floatability and electrokinetic potential has been widely used, mainly for judging the behaviour of reagents 6,7 In this study, the electrokinetic . potential was obtained from the electrophoretic mobility of fine coal particles floating in a slurry with distilled water.

A high-volatile bituminous coal was extracted at room temperature by various organic solvents. The yields of the extracts ranged from 4.5 wt% daf (ethanol/benzene extract) to 38 wt% daf (pyridine/ethylenediamine extract). The extracts were analysed by FI mass spectrometry; the volatile part (75-80 w
Several Canadian coals were analysed by FT-i.r. The technique is applicable to both the organic and inorganic part of the coal. The method by which the spectra can be subtracted one from the other, allows the distinguishing of one coal from another by characteristic functional groups. The high resol
