Location and distribution of inorganic material in a low ash yield, subbituminous coal

Previous studies of mineral matter in low ash yield, low rank coals have suggested that much of the inorganic material is present as organically bound elements rather than as discrete minerals. This study investigates the location and occurrence of this inorganic material to the angstrom level using...

Description
Summary:Previous studies of mineral matter in low ash yield, low rank coals have suggested that much of the inorganic material is present as organically bound elements rather than as discrete minerals. This study investigates the location and occurrence of this inorganic material to the angstrom level using non-invasive small angle scattering techniques. Microstructural analysis conducted on matrix and vitrain samples, collected from the subbituminous coals of the Huntly coalfield, found that the inorganic material is located in the 12.5Å
