Thermal testing methods in determination of characterization of charcoals

Abstract

Thermal analysis testing methods were used in determination of the characterization of charcoals. Thermogravimetry (TG) method was adopted to determine the composition of charcoals, which include moisture, volatiles, fixed carbon and ash contents. The result showed that this method could detect the subtle change of charcoal composition, even the variation of different parts of material. Differential Thermal analysis (DTA) and related methods were also used to investigate reactivity of charcoals. The ignition temperature decrease with increasing carbon content was detected by these methods.
