The chemical percolation devolatilization model applied to the devolatilization of coal in high intensity acoustic fields
(Soc Brasileira Quimica, 2002-05-01)
The chemical percolation devolatilization model (CPD) was extended for the prediction of drying and devolatilization of coal particles in high intensity acoustic fields found in Rijke tube reactors. The acoustic oscillations ...
Identification of acoustic fields in aqueous biomass solutions of banana waste pretreated by power ultrasound
(Springer, 2018-03-01)
High-intensity ultrasound is a technology used to improve the performance of processes in the chemical, pharmaceutical, biomass pretreatment, and food industries. However, few studies were described in the literature to ...
