We developed a simple, scalable and reliable pyrolysis reactor to carbonize cashew nutshells. Good quality charcoal was obtained, and also the possibility of recovering cashew nutshell liquid (CNSL) and bio-oil was deemed as feasible.

This project was funded by the Cooperation Chair, University of Zaragoza.

Project results are summarized in these publications:
