| Abstract: | Several ways have been used to analyze the XRD graphics of chars and slags which were produced in the H 2/Ar DC plasma jet with coals and liquefied gas. With the different conditions and different region of plasma jet, the order of C atoms and the structure of chars and slags are different. The X ray radial distribution function (RDF) was discussed and used to determine the structure of slags. The main aim is to clear the process of the mechanism of deposition on the reaction wall and plasma reaction.; |
