1 Miller, Jan D.Axial flow reversal and its significance in air-sparged hydrocyclone (ASH) flotationIn recent years the potential of air-sparged hydrocyclone (ASH) flotation for fine coal cleaning has been demonstrated both in pilot plant testing and in a plant-site demonstration program. Further improvements in the ASH technology will depend, to some extent, on improved understanding of the co...Flotation; zero axial velocity; computational fluid dynamics1995
2 Miller, Jan D.; Lin, Chen-LuhCapillary network model for filter cake based on pore structure analysisDewatering of fine coal by continuous filtration involves filter cake formation and removal of surface moisture by drawing air through the capillaries of the cake. In order to gain a better (understanding of the complex transport phenomena that occur in the filter cake, analysis of the effect of t...pore geometry; transport properties; microtomography1996
3 Miller, Jan D.; Lin, Chen-LuhFine coal washability-liberation analysis by cone-beam X-Ray microtomographyA new method based on cone-beam x-ray microtomography is described for direct determination of the three-dimensional liberation spectrum of multiphase particles 100 microns in size or less. Such a technique may provide the basis for more detailed and accurate washability analysis in fine coal chara...spectrum; sink-float; density1996
4 Miller, Jan D.;Yu, QiangFossil resin, a value-added product from western coalCertain bituminous coals of the western United States are known to contain appreciable quantities of macroscopic fossil resin (resinite). Such resinous coals are found in the states of Arizona, Colorado, New Mexico, Utah, Washington, Wyoming, etc. The Wasatch Plateau coal field in Utah (Figure 1)...resinite; solvent refining; Wasatch plateau; hydrogenation1992
5 Miller, Jan D.;Yu, QiangSolvent refining of coal resin concentratesCertain bituminous coals of the western United States are known to contain appreciable quantities of macroscopic resinite (fossil resin). Such resinous coals are found in the states of Arizona, Colorado, New Mexico, Utah, Washington, Wyoming, etc. Among these, the Wasatch Plateau coal field in ce...1994
