Abstract

Coal tar pitches are widely used as a binder in the production of carbon artifacts, and during baking of these artifacts significant amounts of polyaromatic hydrocarbons (PAHs) are emitted. This study has identified a green engineering approach to reduce the emissions of PAHs from coal tar pitches using a wide range of environmental benign polymerization additives that increase the yield of the carbon artifacts during baking. These additives have been tested against conventional sulfur additives, and an improvement of 97% in the pitch retention levels was observed. Several techniques, including pyrolysis GC/MS studies, were used to ascertain the role of the polymerization additives during the pyrolysis of coal tar pitches. It was observed that the novel additives react with the low molecular weight compounds present in the pitch.
