Answer 2

Proximate analysis of coal determines the moisture content of coal,volatile matter,ash content and fixed carbon of coal. Ultimate analysis determines the chemical composition of coal i.e Carbon,hydrogen,oxygen,nitrogen,sulphur along with moisture and ash.

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. ...
