- Eventhough a microbalance is an experimentally convenient, widely used method of measuring the gasification rates of carbonaceous materials, problems arise in the interpretation of the measurements. Expressing the change of sample weight with time as a single measure, such as reactivity, has not been standarized The present study utilized an improved analytical technique for calculating the kinetic parameters from coke gasification data. The kinetics of coke gasification were investigated using Thermogravimetry Analyzer (TGA) in the range 25 to 800°C at atmospheric pressure. The activation energy appears to depend linearly on conversion up to 0.5 conversion level and then the activation energy remains constant at 23 kcaUgmole.
