Abstract

<!--[if !vml]-->Abstract Image<!--[endif]-->

One of the key challenges in reforming military fuels for use with fuel cells is their high sulfur content, which can poison the fuel cell anodes. Sulfur-tolerant fuel reformers can convert this sulfur into H2S and then use a desulfurizing bed to remove it prior to the fuel cell. In order to optimize and verify this desulfurization process, a gas-phase sulfur analyzer is required to measure H2S at low concentrations (<1 ppmv) in the presence of other reforming gases (e.g., 25–30% H2, 10–15% H2O, 15% CO, 5% CO2, 35–40% N2, and trace amounts of light hydrocarbons). In this work, we utilize near-infrared cavity-enhanced optical absorption spectroscopy (off-axis ICOS) to quantify H2S in a JP-8 fuel reformer product stream. The sensor provides rapid (2 s), highly precise (±0.1 ppmv) measurements of H2S in reformate gases over a wide dynamic range (0–1000 ppmv) with a low detection limit (3σ = ±0.09 ppmv in 1 s) and minimal cross-interferences from other present species. It simultaneously quantifies CO2 (±0.2%), CH4 (±150 ppmv), C2H4 (±30 ppmv), and H2O (±300 ppmv) in the reformed gas for a better characterization of the fuel reforming process. Other potential applications of this technology include measurement of coal syngas and H2S in natural gas. By including additional near-infrared, distributive feedback diode lasers, the instrument can also be extended to other reformate species, including CO and H2.
