The objectives of the five tasks are as follows: (1) determine the volatility and to characterize the aromatic and fuel-N compounds present in a typical synfuel; (2) determine the aromatic and fuel-N characteristics of narrow (50/sup 0/C) distillation cuts of synfuel as a function of time, temperature and oxygen level; (3) determine the ease of oxidation of the pyrolysis products; (4) define the burning characteristics of synfuel as a function of equivalence ratio, temperature and residence time in two-stage combustion; (5) apply the results from Tasks 2, 3 and 4 into existing models for soot and NO/sub x/ formation in flames. Results obtained on total nitrogen analyses of the fuels and condensable products have been found to lack needed precision and accuracy. Test samples are currently being analyzed by a third laboratory. A similar series of test done to evaluate the titration method for the determination of basic nitrogen has shown excellent precision and accuracy. Pyrolysis and oxidative experiments have been extended to 1100/sup 0/C ad the percent of stoichiometric oxygen to 70% of the oxygen required for complete combustion. The resulting condensible products require changes in the procedures previously used for analysis because they contain solids and/or significant amounts of water. No analytical results are available at this time. A two-staged combustor capable of burning up to 0.5 gal SRC II per hour has been built for the Task 4 experiments. The combustor is designed with a secondary air inlet and sampling probes for liquid and gaseous products.
