Abstract

Methylcyclohexane, a candidate endothermic fuel, was the focus of the present research, a study of the effects of pressure on the formation of large PAH under supercritical pyrolysis conditions. For this purpose, pyrolysis experiments were conducted with methylcyclohexane (critical temperature, 299 °C; critical pressure, 34 atm) in an isothermal silica-lined stainless steel coil reactor. The experiments are conducted at a fixed temperature of 570 °C and a fixed residence time of 140 sec. Pressure is varied, experiment to experiment, over the range of 60-100 atm. Ranging in size up to 10 fused aromatic rings, the largest product PAH include: anthanthrene, coronene, naphtha[2,1,a] pyrene, 1-methyl coronene, benzo[a]coronene, benzo[pqr]naphtho[8,1,2-bcd]perylene, naptho[8,1,2-abc]coronene and ovalene. Most of the PAH identified in the methylcyclohexane products are found in the products of the supercritical pyrolysis experiments with toluene, the dehydrogenation product of methylcyclohexane. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
