U.S.-Canada Cooperative Research: The Effect of Size and Distribution of Inorganic Mineral Particles in Coal Maceral on its Wettability

9819332 Drelich该奖项将支持美国- Jaroslaw Drelich博士，密歇根理工大学和Janusz S.加拿大不列颠哥伦比亚省大学的Laskowski教授研究了煤中无机矿物颗粒的尺寸和分布对其润湿性的影响。 特别是，利用先进的现代技术，研究人员将研究煤的无机杂质的性质，数量，大小和分布对前进和后退接触角的影响，这会影响其润湿性。由于选煤厂的选煤和重组过程在很大程度上取决于煤中有机质和矿物质组分的润湿性，因此该研究具有重要意义。 加拿大方面将提供不列颠哥伦比亚省大学提供的低温灰化技术，并贡献他们在煤表面科学方面的专业知识，而美国研究人员将带来使用显微探测和X射线衍射仪器的现代技术，这将促进对实验数据的解释。 拟议的工作将为煤显微组分的水润湿性提供一个改进和扩展的数据库，这可能会减轻北美煤炭使用对环境的影响。

9819332DrelichThis award will support a U.S.-Canada collaboration between Dr. Jaroslaw Drelich, Michigan Technological University and Dr. Janusz S. Laskowski of the University of British Columbia, Canada to study the effect of size and distribution of inorganic mineral particles in coal on its wettability. In particular, using advanced modern techniques, the researchers will study the effects of the nature, amount, size, and distribution of inorganic impurities of coal on both advancing and receding contact angles, which affect its wettability. The research is important because coal separation and reconstitution processes in coal preparation plants largely depend on the wettability of organic and mineral matter constituents of coal. The Canadian side will provide access to a low-temperature ashing technique available at the University of British Columbia and contribute their expertise in coal surface science, while the U.S. researchers will bring modern techniques, using microprobing and X-ray diffraction instruments, that will advance the interpretation of experimental data. The proposed work will produce an improved and extended database for the water wettability of coal maceral that may lessen the environmental impact of coal use in North America.***
