Investigation of the distribution of tar components by fractions as a function of the tar moisture level

An investigation of the fractions obtained in the refining of coal tar was presented. The concentrations of the various components of the fractions were determined as a function of the moisture. Six fractions were obtained--a light fraction, a phenolic fraction, a naphthalene fraction, a wash oil fraction, and two anthracene fractions. An increase in moisture level of the tar caused high losses of naphthalene to the light and phenolic fractions and decreased the quality of the wash oil. The use of a steam stripper to remove naphthalene from the wash oil fraction reduced the effectiveness of the wash oil for recovery of benzene from coke oven gas.
