Coal Wikipedia

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seamsCoal 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

Coal gasification is a production process in which coal is used as raw material and a series of chemical reactions occur between organic substances and gasifier agent in coal under high temperature and pressure in a specific equipment (such as gasifier), so as to convert solid coal into combustible gas After gasification, coal burns more fully and is more conducive to transportation and storage

COAL CHARACTERISTICS Purdue University

Anthracite coal is a dense, hard rock with a jetblack color & metallic luster It contains between 86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke Bituminous coal (in Indiana), contains between 69% & 86% carbon by weight Subbituminous coal contains less carbon, more water & is a less efficient source of heat Lignite coal, or brown coal, is a very
