Mechanical/thermal dewatering of lignite. Part 3: Physical properties and pore structure of MTE product coals

Comparing the porosity and surface areas of coal as measured by gas adsorption, mercury intrusion and SAXS techniques

“…MIP is another standard method of determining the porosity and surface areas of coals, but is limited only to meso-and macro-porosity [27][28][29][30][31][32][33][34][35][36][37][38]. Although the application of the macroporosity of coals to most of its utilisation processes is still very limited, the understanding of this property is relevant in predicting total gas capacities of coals when used for CO 2 sequestration [39].…”

A comparison of acid treatment in the dewatering of Chinese and Australian lignites by mechanical thermal expression at high temperatures

“…The MTE dewatering device and the experimental procedure have been provided in the literature [21][22][23]. The diameter of the cell used is 50 mm and the pore size of the sintered plate filter in the bottom is 40 μm.…”

“…It is necessary to correct the Hg pore volume data for interpretation [24,25]. In this study, the compressibility correction method developed by Bergins [21] was applied and all the results were reported on a dry basis. The pore volume for each range of pore diameter was determined by differentiation of the cumulative mercury intrusion volume.…”

Investigation on Pore Structures of a Medium Volatile Bituminous Coal with Solvent Extraction Tests

“…SAXS and SANS technologies are generally useful in determination of coal pore structure and porosity, can provide very valuable information in the fundamental study of coal. However, the mercury injection porosimetry is still very useful in the study of coal structure, particularly in providing quantitative information on the pore structure of coal under a reasonably small pore size (Toda and Toyoda, 1971;Mahajan, 1984;Kloubek, 1994;Bergins et al, 2007;Friesen and Ogunsola, 1995;Qu et al, 2010).…”
