2013-11-1  Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster. It contains between 86% and 98% carbon by weight, and it burns slowly, with a pale

Small-molecule gas sorption and diffusion in coal

2010-7-1  Abstract. Injections of carbon dioxide (CO 2) into unmineable coalbeds can both enhance coalbed methane recovery (ECBM), a high-efficiency energy, and realize underground storage of CO 2. In these processes, the diffusion and sorption of methane (CH 4) and carbon dioxide are key dominant processes. In this study, the diffusion and sorption behavior
