Coupling of an acoustic emissions system to a laboratory torrefaction reactor

Silveira E., Girão de Morais M.V., Rousset P., Caldeira Pires A.D.A., Pétrissans A., Oliveira Galvão L.G.. 2018. Journal of Analytical and Applied Pyrolysis, 129 : p. 29-36.

This article describes the use and characterization of an acoustic system coupled to a torrefaction reactor. The reactor, including phase shift and frequency, was characterized by applying both Lissajous/Hilbert and cross-spectrum techniques. Optimum acoustic frequencies were identified and an exploratory torrefaction test combining frequencies and temperatures was performed. The results from dynamic solid yields, conversion rates and temperature profiles showed that acoustic fields may improve torrefaction treatment. (Résumé d'auteur)
