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

9819332该奖项将支持密歇根理工大学的Jaroslaw Drelich博士和加拿大不列颠哥伦比亚大学的Janusz S.Laskowski博士之间的美加合作，研究煤中无机矿物颗粒的大小和分布对其润湿性的影响。特别是，研究人员将利用先进的现代技术，研究煤中无机杂质的性质、数量、大小和分布对推进和后退接触角的影响，这将影响其润湿性。这项研究很重要，因为选煤厂的煤炭分选和重组过程在很大程度上取决于煤的有机和矿物质成分的润湿性。加拿大方面将提供不列颠哥伦比亚省大学可用的低温灰化技术，并提供他们在煤炭表面科学方面的专业知识，而美国研究人员将带来现代技术，使用微观探测和X射线衍射仪，这将促进对实验数据的解释。拟议的工作将建立一个改进和扩展的煤显微组分水润湿性数据库，可能会减少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.***
