Coal Hydrogenation and Environmental Health
The conversion of coal to desirable solid, liquid, or gaseous products, or to usable energy, is an im-portant aspect of an industrialized society. Because of the demand for low-sulfur, environmentally ac-ceptable fuels, coal liquefaction and gasification are of particular interest at the present time.

Elucidation of the Influence of Coal Properties on Coal
Pyrolysis is the first step in most coal conversion processes such as combustion, gasification and liquefaction. Coal char combustion is influenced by a wide variety of parameters (burnout time, heat release, mineral matter content etc.) which are factored into the reactivity of the char. On heat treatment, the coal particles undergo thermo-

Different uses of coal require different quality parameters. For example, high amounts of pyrite and other ash-forming minerals in coal are undesirable in coking and combustion, but may be beneficial in certain liquefaction reactions.
