Detection and differentiation of C4 hydrocarbon isomers over the Pd-SnO2 compressed powder sensor

Abstract:

The detection and differentiation of C4 hydrocarbon gases, including n-butane, 1-butene, iso-butylene, cis- and trans-2-butene are investigated over a palladium-promoted tin oxide sensor using AC impedance. It is found that 1% Pd-SnO2 gives a good linear response and good sensitivity with respect to a wide range of n-butane concentrations (0-10,000 ppm). At high operation temperatures (≥400 °C), the tin oxide-based sensor offers no differentiation on different C4 gases and is consistent with ...
