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-
