Abstract
This work investigated the effect of oxygen concentrations in the reactor on the partial oxidation of JP8 under the distributed reaction condition. Reforming efficiency as high as 74% was achieved; syngas composition consisted of 20.7 to 22.3% hydrogen and 20.2 to 21.5% carbon monoxide. Reformate product distribution and quality was found to depend on the reactor oxygen concentrations and to a lesser extent on flame regime. Addition of oxygen enhanced the extent of reforming reactions, to promote increased conversion and reforming efficiency.
