Effect of Analysis Temperature on Identification of Soot by Pyrolysis Gas Chromatographyt

Abstract

Approach for identifying the soot obtained by combustion of benzene, toluene, o-, m-, p-xylene, ethylbeinzene, styrene and cumene was carried out by means of curie point pyrolysis gas chromatographic method. The soot was collected outside the diffusion flame. The pyrolysis temperature was changed from 170°C to 764°C. Biphenyl in the benzene soot ana xvlene in the xylene soot were useful specific components for identification of the soot. Pe ak ratio of benzene and toluene was also available for identification of the soots. As the result of examination both on the peak ratio of these specific components to others, and on peak ratio of benzene to toluene in the pyrogram, the most suitable pyrolysis temperature for ii-lAntiratinn of soot was determined to be 590°C. t Studies on Identification of Soot.
