Abstract

The organic components in coal tar from the waste dumps at Qarmet coke plant are identified by gas–liquid chromatography. The analysis yields the following results: 29.41% naphthalene and its derivatives; 3.42% acenaphthene; 3.94% dibenzofuran; 4.18% fluorene; 4.98% phenanthrene; 0.91% anthracene; 2.45% fluoranthene; and 0.94% pyrene. Medium-temperature pitch is obtained by vacuum distillation of coal tar from dump 1 at the Qarmet plant. Many characteristics of the pitch—such as the content of toluene-insoluble components (40.56%), softening temperature (85–90°C), and yield of volatiles (54%)—correspond to the standard for grade-B electrode pitch.
