Quantitative and kinetic TG-FTIR study of biomass residue pyrolysis: Dry distillertextquoterights grains with solubles (DDGS) and chicken manure

New energy policies all over the world are trying to tackle high oil prices and climate change by promoting the use of biomass to produce heat, electricity and liquid transportation fuels. In this paper we studied two different secondary fuels: dry distillertextquoterights grains with solubles (DDGS) and chicken manure. These materials have high content of nitrogen and ashes which limit their usage in thermal applications due to potential excessive NOx emissions and problems of slagging, fouling, corrosion and loss of fluidization.The fuels tested here were received from industrial partners. In order to reduce the ash content the fuels were pre-treated using water leaching pre-treatment.Pyrolysis of these fuels has been monitored through a TG-FTIR set-up. Quantification of the following volatile species was possible: CO, CO2, CH4, HCN, NH3, HNCO, H2O.The water leaching appeared to decrease the amount of ashes in both samples and remove some of the troublesome compounds like Cl, S and K.The DDGS thermogravimetric curve showed three main peaks at 280?textdegreeC, 330?textdegreeC and 402?textdegreeC with a total weight loss of around 79     «
