Autor: Lanjun Zhang, Zenghua Li, Jinhu Li, Yinbo Zhou, Yongliang Yang, Yibo Tang

Publikováno v: Molecules, Vol 20, Iss 12, Pp 22241-22256 (2015)

This paper selects two typical compounds containing organic sulfur as model compounds. Then, by analyzing the chromatograms of gaseous low-temp oxidation products and GC/MS of the extractable matter of the oxidation residue, we summarizing the mechan

Factors impacting gas content measurements using gas desorption by drilling underground boreholes

Autor: Zenghua Li, Qiangqiang Qi, Yongliang Yang, Yinbo Zhou, Bin Wang

Publikováno v: Adsorption Science & Technology, Vol 34 (2016)

Accurate determination of the gas content in coalbeds is important for safe mining. Currently, gas desorption by drilling underground boreholes is the most commonly used gas determination method. However, this method is not very accurate and needs to

Research on the Composition and Distribution of Organic Sulfur in Coal

Autor: Lanjun Zhang, Zenghua Li, Yongliang Yang, Yinbo Zhou, Jinhu Li, Leilei Si, Biao Kong

Publikováno v: Molecules, Vol 21, Iss 5, p 630 (2016)

The structure and distribution of organic sulfur in coals of different rank and different sulfur content were studied by combining mild organic solvent extraction with XPS technology. The XPS results have shown that the distribution of organic sulfur

The role of graphite in the formation of unconformity-related uranium deposits of the Athabasca Basin, Canada: A case study of Raman spectroscopy of graphite from the world-class Phoenix uranium deposit

Autor: Hao Song, Guoxiang Chi, Kewen Wang, Zenghua Li, Kathryn M. Bethune, Eric G. Potter, Yongxing Liu

Publikováno v: American Mineralogist. 107:2128-2142

The unconformity-related uranium (URU) deposits in the Proterozoic Athabasca Basin (Canada) represent the richest, and one of the most important, uranium endowments in the world. Most of the URU deposits are associated with pre-existing graphitic bas
