Comparison of sintering and compressive strength tendencies of a model coal mineral mixture heat-treated in inert and oxidizing atmospheres

Nel, Marika V.; Strydom, Christien A.; Schobert, Harold H.; Beukes, J. Paul; Bunt, John R. (Elsevier, 2011)

The chemical interactions responsible for sintering in a coal mineral mixture were investigated in air and in N2. A mineral mixture was made up by mixing kaolin, pyrite, quartz, calcite, hydromagnesite, FeCO3 and anatase ...
Development of a Pt/stainless steel mesh catalyst and its application in catalytic hydrogen combustion

Du Preez, S.P.; Bessarabov, D.G.; Falch, A.; Jones, D.R.; Mota das Neves Quaresma, C. (Elsevier, 2019)

In this paper, different methods to prepare a Pt/stainless steel mesh catalyst for catalytic hydrogen combustion are reported. Pt was deposited as a thin layer onto stainless steel mesh as a support matrix. Thermal treatment ...
Effect of sodium compounds on the sintering propensity of coal-associated minerals

Nel, Marika V.; Strydom, Christien A.; Schobert, Harold H.; Beukes, J. Paul; Bunt, John R. (Elsevier, 2015)

This study focused on the chemistry involved in sintering of coal-associated minerals during combustion and inert conditions. Changes in mechanical strength were recorded with compressive strength measurements. This method ...
