91. Coal Decomposition by Microwave Plasma Technique : Effect of Plasma Source on Coal Conversion and Product Distribution

Abstract

Using helium or carbon dioxide as plasma sources, Yalloum coal decomposition by microwave plasma technique was performed. Changes with the content of C, H, O from untreated coal into oily products, gaseous products and residue were observed. This report described the roles of carbon dioxide during plasma reactions with regard to higher reactivity of coal and selective synthesis of chemical feed-stock gases or fuel oils.
