16. Continuous Measurement of Change in Oxygen Content of Carbonaceous Materials during the Gasification

Abstract

The amount of oxygen uptake on carbons during the gasification was estimated by continuously measuring the weight change and the gaseous products. A sensitive thermobalance and a efficient mass spectrometer were used for this purpose. Step response experiments for ^<18>O_2 injections were also performed to examine the transient behavior of the gasification reaction. The role of adsorbed oxygen in the gasification mechanism was examined in detail based on these experiments.
