How should a company select impellers for lignocellulosic hydrolysis reactors? Lignocellulosic slurries at high solids concentrations (10-30%) can be quite viscous. The author has seen somewhere the viscosity at a shear rate of 1/s is…

Hydrofoil Impellers vs. Pitched Blade Turbines in Lignocellulosic Slurries
In a previous article (ref 1), it was stated that both pitched blade turbines and hydrofoils could be successfully used to agitate high-solids lignocellulosic materials, but that the hydrofoil could do the job with less…

Aerobic Fermentation Processing
Bio-processing may involve aerobic fermentation, whereas ethanol and chemicals from starches and lignocellulosic materials are generally anaerobic processes. Aerobic fermentation is a metabolic process by which cells metabolize sugars via fermentation in the presence of…
