Samples from the Tavantolgoi coal deposit were analyzed by petrographic, elemental, FT-IR, XRD, and float-and-sink tests. The deposit is Permian age and characterized by lithotypes that are bright, semi-bright, semi-dull, and dull. Microscopically identified macerals in the deposit are fusinite and vitrinite components and minerals. The inorganic elements in the deposit are Si and Al, indicating an...
This report outlines results of an investigation of the composition of bone pyrolysis tar produced in Mongolia. The liquid product (tar) yield was low: ~4.9%. The elemental composition of the tar was C: 73.3%, H:10.1%, N: 11.3%, O: 5.3%. Size-exclusion chromatograms signalled the presence of generally smaller mass material than coal tars and pitches, with a range from about 2000 U downwards. GC-MS...
