NOx and N2O Precursors (NH3 and HCN) in Pyrolysis of Biomass Residues

Abstract: Nitrogen release is a little known aspect of pyrolysis of biomass. In this study on thermally thick samples of three biomass residues with high N-content, the NO x precursors NH 3 and HCN were measured with a Fourier transform infrared (FTIR) analyzer at different heating rates (low and high) and temperatures (400-900 °C). The feedstocks investigated have been given scarce or no attention. At a high heating rate, (1) NH 3 is the main N-compound with increasing yield with increasing temperature until reaching a… Show more

“…A similar inference has been made by Tian et al [191]. NH 3 also increase with temperature but reaches a maximum around 1023-1173 K as has been observed by many researchers [181,191]. It has also been observed that further increases in temperature cause a decrease in NH 3 concentration in the gas [165,181,192,193] at temperatures higher than 1073-1173 K. This behavior could be explained by the conversion of ammonia into N 2 and H 2 as suggested by [165]:…”

“…Becidan et al [181] observed an abrupt increase in N-conversion to HCN with temperature. They inferred that this observation is the result of tar and volatile cracking as well as secondary reactions.…”

“…HCN has previously been observed from field biomass fires (Hurst et al, 1994a, b;Goode et al, 2000a;Yokelson et al, 2007b;Crounse et al, 2009) and using laboratory biomass combustion systems (Lobert et al, 1991;Holzinger et al, 1999;Christian et al, 2004;Becidan et al, 2007). Column measurements of HCN were measured from the International Scientific Station of Jungfraujoch (ISSJ) by solar infrared (IR) spectroscopy in 1998 during an intense period of biomass burning in the tropics .…”

“…Pyrolysis of nitrogen atom (N)-containing functionalities in the fuel is the primary mechanism proposed for HCN release from biomass combustion (Johnson and Kang, 1971;Glarborg et al, 2003). Hydrogen cyanide has been measured from field biomass fires (Hurst et al, 1994a, b;Goode et al, 2000;Yokelson et al, 2007;Crounse et al, 2009), and from laboratory biomass combustion systems (Lobert et al, 1991;Holzinger et al, 1999;Christian et al, 2004;Becidan et al, 2007). Elevated free tropospheric HCN columns were measured from the International Scientific Station of the Jungfraujoch (ISSJ) in the Swiss Alps by solar infrared (IR) spectroscopy during 1998, coinciding with a period of intense BB in the tropics (Rinsland et al, 2000).…”
