|a Our efforts this quarter were directed at preparing PAH samples at well-controlled extents of primary devolatilization. In the long (12.5 cm) hot zone, Preliminary studies with a Pit. No. 8 hvA bituminous coal showed that a furnace temperature of 1380 K yields the best resolution of primary devolatilization from secondary pyrolysis. There is no soot at all in the PAH samples collected during the first half of tar evolution. Although some soot is present in the total sample of all tar from primary devolatilization it never amounts to more than 10 % of the aerosol and is usually less than 5 %. Also, the maximum weight loss observed with the new operating conditions is nearly 50 wt. % daf, which compares favorably to our previous value of 55 wt. % for this coal. Regarding PAH analysis during this quarter, the assembly of the gravity-flow column chromatographic system for prefractionating the coal tar was completed. Standard compounds spanning a wide range of polarities and molecular weights were selected and purchased. These compounds were utilized to begin testing and refining the prefractionation procedure.
