Coal - Wikipedia

Coal is a coustible black or brownish-black sedimentary rock , formed as rock strata called coal seams . Coal is mostly carbon with variable amounts of other elements , chiefly hydrogen , sulfur , oxygen , and nitrogen . Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal

Influence of Coke and Graphite on the Decomposition and

DP50 were 112 μm for coke and 170 μm for graphite. Thus, from these values it is observed that coke has a PSD finer than graphite. Morphology of coke particles is spherical/round in shape (Fig. 3). Coke particles are around 10 μm in size but they form agglomerates. In Fig. 3 it is observed agglomerates higher than 100 μm.

An evaluation of desulfurization technologies for …

The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure alytic process. This makes HDS a very costly option for deep desulfurization. Moreover, HDS is not effective for removing heterocyclic sulfur compounds such as dibenzothiophene (DBT) and its derivatives, especially 4,6-dimethyldibenzothiophene (4,6-DMDBT).
