Effect of Heat on Organic and Inorganic Components in Some Non-coking Lower Gondwana Coals

The concentration of different maceral groups and minerals in coal influence the quality as each them behaves differently during heat treatment. purpose this study is to know how these are behaving at temperature conditions. Therefore, various macerals were concentrated by using heavy liquids specific gravities (1.3, 1.7 1.9). generated density fractions treated with 400, 600, 800 1000 °C. All conditions along feed sample investigated optical microscopy, X-ray diffractometry, electron-probe microanalysis Fourier transform infrared spectroscopy analysis. results suggest that fusinite sclerotinite most stable macerals, whereas quartz mineral. Telocollinite found be oxidized very prominently 400 Siderite pyrite alter form hematite above °C °C, respectively. Kaolinite converts metakaolin followed mullite increasing temperature.
