摘要：
Experimental work was carried out to study the kinetics of the carbon-dioxide gasification of a coal char. The coal char was prepared from Australian bituminous coal by pyrolysing at 900 degrees C in a tube furnace for 9 minutes in inert environment. The coal char were gasified in a Thermo-Gravimetric Analyzer (TGA) with mixture of carbon. dioxide, and nitrogen. The effects of gasification temperature (800-875 degrees C) and carbon dioxide concentration. (10-80%) were studied. In the present study the reaction rate of the pyrolysed coal was obtained and interpreted by,Random Pore. Model.
