Project Description

i. A tunable diode laser spectroscopy (TDLS) system is currently under development to simultaneously make absolute measurements of the mole fraction of methane, water vapour, carbon dioxide and carbon monoxide for real-time monitoring of the ethanol autothermal reformation (ATR) process. Ethanol ATR is an important process for the generation of hydrogen from hydrocarbon compounds. The key to commercialization of the reformer system is its ability to operate in real-time under variable load condition.

ii. This requires extensive characterization of the reformation process with respect to their dynamics and response to fluctuating load, i.e. hydrogen demand. Real-time continuous monitoring of the reformate is essential to ascertain the system’s operating parameters. This project uses the powerful TDLS technique comprising four narrow linewidth mid-infrared quantum cascade laser diodes whose emissions wavelengths are matched to non-overlapping absorption lines of these gases.

iii. TDLS is ideally suited for this purpose because the measurements are absolute in nature (no calibration required), highsensitivity (low ppm to ppb), in situ, non-invasive concentration measurements of the four gases can be made simultaneously with very low cross-sensitivity. The project will use recently developed calibrationfree second harmonic wavelength modulation spectroscopy (2f WMS) algorithms to extract the mole fraction of the four gases at temperatures as high as 900 Celcius. Such a system will help to optimize the reformation process and to detect catalyst degradation.
