Gas-phase hydrodesulfurization of a JP-8 light fraction was investigated over CoMo/Al2O3 and NiMo/Al2O3 catalysts. Use of a light fraction provides a fuel that is more easily desulfurized and allows the process to operate in the vapor phase. This study investigated the utilization of reformate ( syngas) from a steam reformer rather than pure H-2 as gas feed to HDS unit. This is consistent with what might be available to the military during operation in the field. Dry syngas functions almost as well as pure H-2 in the HDS reaction, and sulfur levels below 5 ppmw are readily obtained from a feed initially containing 320 ppmw sulfur. Addition of 40 vol % steam to the syngas has a significant negative impact on HDS performance with CoMo/Al2O3, but only a small effect with NiMo/Al2O3. The impacts of various process conditions on S removal efficiency were examined and will be described.
