Paleoenvironmental, paleoecological and thermal metamorphism implications on the organic petrography and organic geochemistry of Tertiary Tanjung Enim coal, South Sumatra Basin, Indonesia
… studies have been conducted on Tertiary age coals from Tanjung Enim, South Sumatra Basin, Indonesia. The coals are of subbituminous rank (vitrinite/huminite reflectance, VRr, = 0.35 - 0.46%). In this area, the coals were also locally intruded by andesitic sills. The thermally metamorphosed …

An investigation into the bioconversion of South African sub-bituminous coal by Trametes species and Trichoderma atroviride
… processes to yield value-added compounds. Low rank coals (LRC), which are less desirable for combustion processes than high rank coals, are more amenable to biodegradation due to their high moisture content and oxygen-containing functionalities. LRC are therefore ideal for application to …

Processing of Low Rank Coal and Ultrafine Particle Processing by Hydrophobic-Hydrophilic Separation (HHS)
… of ultra-fine mineral particles and low rank coal using the hydrophobic--hydrophilic separation (HHS) method. Several explorative experimental tests have been carried out to study the effect of the various physical and chemical parameters on the HHS process. In this study, the HHS process …
