Thermal Indices
| January 29, 2014 | Filled under Com II |
|
Aim This working group was established in 1988 at the ICCP Meeting in Aachen. The aim was to look at the various thermal indices (i.e., vitrinite reflectance, fluorescence, thermal alteration index, Rock-Eval, volatile matter, elemental composition) in respect to their sensitivity at different rank levels, their limitations and the correlations and comparabilities amongst them. Objectives […] more

This Editorial Group is preparing the Chapter “Coal Mineral Matter characterization by QEMSCAN” for the New Edition of ICCP Handbook. more
Characterization of Gasification Products Working Group
| November 22, 2013 | Filled under Com III |
|
Aim The working group on Gasification Chars was proposed at the Victoria meeting in 2007, and established at the Oviedo meeting in 2008. The reason for the establishment was based on a question: can gasification chars be classified in the same manner as combustion chars? The aim is to determine if the ICCP proposed classification […] more
Self-heating of Coal and Coal Wastes Working Group
| November 22, 2013 | Filled under Com III |
|
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 […] more
Micro-FTIR WG
| November 20, 2013 | Filled under Com I |
|
Introduction The Micro-FTIR WG was established in 2012 in Beijing with the objective to apply Micro-FTIR measurements on coal macerals. The aim is to analyze various macerals in coals of different ranks and determine coalification parameters. Comparative results from several labs will provide data towards a standardization of the process. more
Distinguishing Features Editorial Group
| November 19, 2013 | Filled under Com I, Editorial Group |
|
Introduction This Editorial Group was established in Beijing in 2012 with aim to write/compile a glossary of distinguishing features for all macerals. The intention is to document features of macerals that will assist the petrographers with their tasks. more
Study the Coal Cleat System by Image Analysis

|
Current activities During the Bandung Meeting 2006 the convenor presented the activities of 2005-2006 and gave new guidelines of the exercise which will be repeated next year because in 2005-2006 only one participant responded. In 2007 the convenor will provide more pictures from different samples in order to study the four parameters that the convenor […] more
Identification and Petrographic Classification of Components in Fly Ashes
| January 29, 2013 | Filled under Com III |
|
Objectives The WG was created in 2005 (Patras, Greece) to identify all the organic and inorganic components in fly ashes by using optical microscopy and to establish an ICCP classification that can be accepted internationally. Activities Further activity During the round robin exercises the fly ash components will be classified following the main criteria: i)- […] more
Application of reflectance for estimation of structural order (Structural Order, SWG)
| January 29, 2013 | Filled under Com III |
|
Objectives Application of reflectance for estimation of structural order of coals and carbon materials Activities in individual years: SWG was established on 53rd ICCP Meeting in Copenhagen (Denmark, 2001). On 54th ICCP Meeting (Mozambique/ South Africa, 2002) in Pretoria, there was presented theoretical background of the issue. In 2003 – 2011 SWG performed 3-stage […] more
Inertinite in Combustion
| January 29, 2013 | Filled under Com III |
|
The inertinite in combustion W.G. was established in 1995 at the Krakow Meeting as the natural evolution of the former Reactive Inertinite W.G., which mainly dealt with the behaviour of inertinite under the conditions prevailing in coke ovens. Once that W.G. accomplished the objectives pursued, it was decided to redirect it to the study of […] more
