Data-constrained modelling of an anthracite coal physical structure with multi-spectrum synchrotron X-ray CT

A tutorial introduction to DCM quantitative characterization and modelling of material microstructures using monochromatic multi-energy x-ray CT

“…Once the dialog appears (as in Figure 9) the check box for "Average" can be selected in the "Data Statistics" section at the bottom right of the dialog. The discrete least-square segmentation and data-constrained linear optimization methods have been used in microstructure characterizations of various material samples, including aerospace paint primers [7][8][9][10][11][12] , oil & gas reservoir rocks 3-5, 8, 13, 14 , and various other materials 15 .…”

Experimental meso scale study on the distribution and evolution of methane adsorption in coal

“…As a natural adsorbent, coal has a great methane adsorption capacity. However, compared with other adsorbents, such as Maxsorb III, ACF, and MOFs [3], the diversity of the macerals, variations in mineral species, and an uneven distribution of pores and fractures in coal create inhomogeneous methane adsorption characteristics [4][5][6], rendering an evaluation of the storage characteristics difficult, and hindering the industrial exploitation of CBM reserves. Past studies have shown that the micro pores (<10 nm) in coal are the main sites of methane storage owing to their large surface area, and that the intercrystalline pores and intragranular corrosion pores of clay minerals also have a fair methane adsorption capacity [1,2,7].…”

Experimental Study of High-Temperature Fracture Propagation in Anthracite and Destruction of Mudstone from Coalfield Using High-Resolution Microfocus X-ray Computed Tomography

“…The analysis methods used for observing the development of microstructures include thin sections, P-wave velocity analysis, micro-computed tomography (CT) scans, elemental analysis, and others. However, X-ray CT scans are used widely for studies on soils and rocks such as sandstone (Dewanckele et al 2012;Mayo et al 2015), quartz monzonite (Heard 1980), oil mudstone (Yang et al 2011), limestone (Vandersteen et al 2003, granite (Zhao et al 2008), and cracks in coal (Van Geet 2001;Mazumder et al 2006;Meng et al 2011;Yu et al 2010Yu et al , 2012Golab et al 2013;Wang et al 2013;Cai et al 2014), as well as for soil and rocks from Mars Rieder et al 2004).…”
