Cashew nut shells are important biomass wastes abundant in most of the tropical countries. As biomass feedstock, they are important energy sources that can play an important role as fuel for energy generation through the ordinary thermochemical processes. However, although this potential as fuel, cashew nut shells are still rarely and weakly studied. In fact, studies on pyrolysis, gasification or combustion of cashew nut shells are not commonly found as it happens with wood related biomasses. On the other hand, it is known that pyrolysis plays a key role in any thermochemical conversion of biomass. In fact, biomass pyrolysis is a complex process that influences any of the three main thermochemical conversion processes of biomass into useful energy. This is due to the fact that pyrolysis characteristics do determine the char quality in which gasification and combustion are heavily dependent. Therefore, characterization of pyrolysis process is essential in thermochemical conversion processes. This makes the study of pyrolysis as mandatory in biomass fuels research. In this study, cashew nut shells are pyrolysed at three different low heating rates (10, 30 and 100°C/mn) using thermogravimetric analyser coupled with Fourier transform infrared spectrometer (TG-FTIR). Gas and tar evolution rates as well as yields and pyrolysis kinetics are obtained and compared with the data available in the literature for wood pellets and Miscanthus Giganteus under the same testing conditions. Further, these results are used as reference data for modeling pyrolysis at high heating rates as l,000and 10,000°C/s. The modeling aims at predicting yields and evolution rates of the pyrolysis products.
