摘要：

Coal tars produced by carbonization of wet charges of one coal blend on industrial and semi-industrial scales with different mean flue temperatures and from a preheated charge of the same blend were studied. These tars were characterized by FT-i.r. and H-1 n.m.r. spectroscopy in addition to the standard analytical methods. They were also separated by extrography into fractions differing in chemical functionality, which were examined by FT-i.r. spectroscopy and g.c.-m.s.. Differences were mainly observed in the proportions of polynuclear aromatic hydrocarbons and nitrogen-containing heteroaromatics. The information can be used as an indicator of the severity of thermal cracking during tar formation in a coke oven.
