【Abstract】 For the fast determination of sulphur forms and quantities in coal, a program controlled temperature increasing combustion technique was used to characterize rapidly sulphur distribution in coal using the thermogravimetry/differential thermal analysis (TG/DTA) combined with sulphur analyzer. Based on the special properties of the air releasing from coal and pyrite in the above condition and compared with the results of some standard sulphur containing compounds in the same conditions, the sulphur forms and quantity in coal can be got easily and rapidly. The result shows that it is convenient for the fast characterization of sulphur in coal and for the desulphurization research.更多还原
