Microscopic constituents in solid residues from households combustion
| October 12, 2021 | Filled under Com III |
|
Introduction Currently, numerous studies on the possible co-combustion of waste and biomass, based on the analysis of ash from household furnaces, are being carried out. These studies are based on physico-chemical analysis. Determining optically recognizable characteristic residues in ashes from unwanted additives burned with fuels will complete and simplify these analyzes. This will also allow […] more
Optimization of reflectance measurements on complex blends WG
| October 11, 2021 | Filled under Com III |
|
During 66th Annual meeting of ICCP at Kolkata during 20-27 September, 2014 the Optimization of reflectance measurements on complex blends working group (WG) was constituted to study the vitrinite reflectance values of complex blends aimed for precise industrial usage. The aim is to reduce and optimise the number of counts of vitrinite reflectance from 1000 […] more
Liquefaction Residues Classification Working Group
| January 11, 2016 | Filled under Com III |
|
General information Liquefaction is the conversion of coal to liquids and can be carried out in terms of hydrogenation (direct liquefaction), pyrolysis and Fischer-Tropsch synthesis (indirect liquefaction). Thereby, pyrolysis takes a unique position since it is not only an independent method for upgrading solid fuels, but also the initial step of most conversion processes (e.g. […] more
The Microscopy of Carbon Materials Working Group
| March 20, 2014 | Filled under Com III |
|
The Microscopy of Carbon Materials Working Group (WG) was activated at the 60th ICCP Meeting in Oviedo, Spain 2008, with the objectives directed to the microscopically characterization of carbon materials derived from coal and petroleum. The WG is focused to consolidating and completing the existent methods developed for carbon materials structural and textural characterization: Describe of the optical appearance […] 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
Study the Coal Cleat System by Image Analysis
| August 19, 2013 | Filled under Com III |
|
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
