Rheology of acid suspensions containing cassava bagasse: Effect of biomass loading, acid content and temperature

Understanding the characterization and rheological behavior of acid suspensions of cassava bagasse provides essential information for the design of conversion processes. Samples with different cassava bagasse concentrations (0–10% w∙w−1), phosphoric acid (0–10% w∙w−1) at temperatures between 278.13...

Zusammenfassung:	Understanding the characterization and rheological behavior of acid suspensions of cassava bagasse provides essential information for the design of conversion processes. Samples with different cassava bagasse concentrations (0–10% w∙w−1), phosphoric acid (0–10% w∙w−1) at temperatures between 278.13 and 318.13 K were submitted to steady-state flow over a wide range of shear rates (1–265 s−1). The biomass particles had considerable residual starch (~50% db), low lignin content and adequate particle size (
