Effect of surface roughness of Chinese sub-bituminous coal on the kinetics of three-phase contact formation

By a News Reporter-Staff News Editor at Energy & Ecology Business -- Data detailed on Fuel Research have been presented. According to news reporting originating in Jiangsu, People’s Republic of China, by VerticalNews journalists, research stated, “In this paper, terminal diameter and expansion velocity of the three-phase contact (TPC) line on the low-rank coal surfaces with different surface roughness were investigated. To eliminate the heterogeneity effect on the hydrophilic surfaces of low-rank coal particles, experimental samples with low ash content were adopted.”

Financial supporters for this research include National Natural Science Foundation of China, China Scholarship Council, Key Supported Discipline of Guizhou Provence.

The news reporters obtained a quote from the research from the China University of Mining and Technology, “Moreover, the analysis result of XPS indicated that there were few hydrophilic mineral particles on the low-rank coal surface. Furthermore, from the analyses of SEM and AFM measurements there are many crevices (pillars, protrusions) of different sizes (height and width) in different local areas of low-rank coal surfaces. Therefore, the three-phase contact lines on the low-rank coal surfaces presented different wetting behaviors.”

According to the news reporters, the research concluded: “It demonstrated that the wetting film diameter became smaller and the expansion velocity of the three-phase contact line was faster while the surface roughness of low-rank coal samples increased.”
