Graphite ash analysis

WebChemical analysis. Proximate and ultimate analysis. Proximate analysis data shows that the samples yield 30-34% volatile matter on a daf basis. The inherent moisture content of the coals ranges between 2.9% and 3.8%, and the ash yield of the samples tested (air-dried basis) ranges between 22.1% and 29.7%. WebResidual carbon impacts the coal ash melting process depending on the type and amount added. Adding coal char and graphite significantly elevates the DT, with a maximum rise of 180 °C observed in RCA-30 %C1. In contrast, activated carbon mainly affects the ST, with the highest increase of 45 °C noted in RCA-30 %C3.
