The compounds in solid, liquid or gaseous states which contain carbon in their molecule are known as organic compounds. There are a large number of organic compounds and therefore a proper systematic classification was required. Organic compounds can be broadly classified as acyclic (open chain) or cyclic (closed chain).

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

The average sulfur removal increased from about 26% to 57% by reducing the coal particle size from 10 to 60 mesh. A lower particle size, 200 mesh, improved sulfur removal marginally to 61%. Increasing the reaction time from 10 to 60 minutes or the O/sub 2/ charge from 10 to 35% of the coal COD resulted in higher BTU loss but with no improvement ...
