Molecular fluorine has been used for the study of coal and a small number of model compounds. It is shown that direct estimates can be made of the carbon aromaticity and of the sensitive carbon in cyclic form. The value for a high-volatile Illinois bituminous coal agrees well with that commonly accepted on the aromatic/aliphatic structural hypothesis and suggests that the polyamantane model is unsatisfactory. The reagent also results in removal of nitrogen and sulphur from coal. 相似文献

A method is developed for determining the coking properties and technological value of coal from newly identified beds or
new sections of existing mines. The coking properties are assessed on the basis of predictions of the strength and reactivity
of coke obtained from batch containing coal from single beds and coal blends. The prediction of coke quality is based on the
chemical and petrographic characteristics of the coal. 相似文献

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 Fl mass spectrometry; the volatile part (75–80 wt%) was composed of substances of molecular weight in the range 70–800 amu, but the compounds in the 200–600 amu range predominated. Over 300 compounds were identified by high-resolution mass spectrometry. The results indicate that compounds < 800 amu constitute at least 30 wt% daf of the analysed coal. 相似文献
