Erroneous Quantification of CO and NH3 by FTIR in the Presence of H2 and H2O in Biomass Steam Gasification Syngas

F. Defoort, S. Thiery & A. Puech
The objective of this study is to investigate the effect of H2 and H2O, which are some of the main species present in the gas phase during steam gasification of biomass, in the quantification of CO and NH3 by FTIR (Fourier Transform Infra Red spectrometry). By comparing micro¬Gas Chromatography (.GC) coupled with Thermal Conductivity Detectors (TCD) and FTIR for CO measurements, a matrix effect of H2 on CO quantification by FTIR was observed. This matrix...
