Objectives:

Self-heating of Coal and Coal Wastes Working Group was established during the Joint Meeting of ICCP/TSOP in Oviedo, Spain (September 21-27, 2008). During the self-heating processes, both organic and mineral matter is undergoing alterations. The degree of these alterations depends on the petrographic properties (maceral composition, previous oxidation and rank) and the temperature as well as the rate and time of heating. Access of air plays also an important role in addition to the size of organic matter and mineral content such as pyrite. The objectives of this working group are:

to gather examples of various forms of transformation of organic matter in coal and coal wastes of various rank
to create a classification of self-heating-induced transformations of organic matter in coal and coal wastes

Keywords:

Organic matter, oxidation, self-heating, pyrolysis, coal wastes
