The technique of Truesdail Laboratories, Inc., using the Kjeldahl method to analyze for total nitrogen in fuel oil samples spiked with compounds containing basic or non-basic nitrogen, was found to be both precise and accurate. Attempts to use a gas chromatograph equipped with parallel FID and thermionic nitrogen detectors to determine total nitrogen in the same spiked fuel samples failed because the basic and non-basic nitrogen gave different responses on the thermionic nitrogen detector. The pyrolysis and oxidative-pyrolysis experiments were extended to 1100 C and approximately 100 percent of stoichiometric oxygen. The resulting partially pyrolyzed and oxidized fuel at 1100 C was a low-volatile, insoluble solid. Based on calculated recoveries of gas, liquid, and solid products, for those experiments where complete product collections were carried out, the mass balances averaged 96.4 percent of the material fed. The chemical properties of the condensed products obtained at the extended reaction conditions were measured and the chemical corrrelations were extended to these conditions. Pyrolysis at 1100 C results in the formation of non-volatile solids containing more than 98 percent carbon and less than one percent each of oxygen, hydrogen and nitrogen. The structure of this non-volatile material is presumably graphitic. The nitrogen analyses suggest that the nitrogen which survives at 1100 C is nonbasic. Under oxidizing conditions, as the concentration of oxygen in the system is increased oxygen is incorporated into the molecules and carbon and hydrogen contents decrease. The formation of unsubstituted organics decreases. Unsubstituted aromatics are presumably oxidized to oxygen substituted aromatics and then to CO/sub 2/, etc. Nitrogen content and basic/nonbasic nitrogen distribution remain constant.
