Microscale simulation of biomass conversion processes with on-line TG/FTIR/MS
- Univ. of Utah, Salt Lake City, UT (United States)
Many biomass conversion processes, including combustion, are initiated by pyrolysis reactions. To understand the processes involved in the inceneration of an industrial wastewater treatment sludge and for predicting its potential products of incomplete combustion, a thermogravimetry based analytical system has been developed to study pyrolytic processes by combination with spectroscopic techniques. Selected lignocellulosic materials as well as a surrogate sludge, based on common Sphagnum peat moss with added polymer suspensions and metal salts, were used for modeling and evaluation of the sludge pyrolysis process. It was achieved by coupling of a Perkin-Elmer model 7 TG analyzer to a Hewlett-Packard benchtop GC/IRD/MSD system via a specially constructed heated transfer line assembly that allows to combine precise temperature information and accurate weight loss with MS and IR response profiles, thereby providing detailed information about accurate weight loss wtih MS and IR response profiles, thereby providing detailed information about mechanisms of underlying degradation processes. The usefulness of the results obtained with the analytical system was further confirmed by the qualitative similarities of the pyrolytic products with products of incomplete combustion detected under oxidative environments using bench scale rotary kiln and fixed bed type reactors.
