Abstract

Most coal research is aimed either directly or indirectly at gasification, pyrolysis, combustion or liquefaction. The 22 papers presented at the 8th ICTA on coal included a wide range of coal or carbon topics. Among these were examination of coal composition by proximate analysis, as well as low-temperature ashing and multiple atmosphere differential thermal analysis, thermogravimetry and differential thermogravimetry for the study of mineral matter content. Devolatilisation products were examined and the effects of pre-treatment on coal thermal degradation. Investigation of new materials included thermally exfoliated graphite made from graphite intercalation compounds, and materials made from cellulose derivatives. New methods of thermal analysis used by some authors included thermomagnetometry and evolved gas analysis, emanation thermal analysis and differential scanning calorimetry. Among the papers presented were a few, only, in the area of coal studies and the usefulness of thermal analysis and thermogravimetric analysis techniques in this area could be expanded greatly.
