Abstract
In the present paper, X-ray photoelectron spectrum (XPS) is used to reveal the surface texture, main elements and occurrence mode of different-density-level sample coal of Fenxi County. The experimental results demonstrate that: (1) there is an extremely low content of nitrogen in the sample coal; (2) carbon mainly exists in the form of C-C and the contents of carbonyl (C=O) and carboxyl is still relatively low; (3) with the increasing of density, such content has a growing trend; (4) the organic sulfur of the coking coal in Fenxi County has the three major forms, i.e., (sub)sulfone, thiophene and thiol (ether), with their respective content in a low-to-high order.
