Thermochemical Conversion of Cashew Nut Shells, an Extractives-rich Biomass

Short Introductive summary

Cashew nut shells (CNS) are non-edible agricultural residues produced by cashew nut shelling units, found abundantly in West Africa. The valorization of these shells is currently problematic due to the fact that they contain up to 40% of acidic extractives, called Cashew Nut Shell Liquid (CNSL).When converted through gasification, this high extractives content is the source of tars in the syngas, which is known to be problematic for useful energy production such as electricity or biofuels. The scientific objective of this study is the understanding of the behavior of CNSL during pyrolysis as well as thermal/catalytic cracking, and reforming that take place in a gasification process. For this, an experimental study supported by specific lab reactors and innovative analytical methods was carried out.
