Impeller Selection for Lignocellulosic Hydrolysis Reactors
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…

Biomass Solids Agitation via Turbine
What percent of biomass solids can be successfully agitated with a turbine agitator? In the early days of the development of biomass hydrolysis reactors, it was common to use rotating barrels (similar to continuous solids dryers),…

Feedstocks for Lignocellulosic Biofuel Production
What feedstocks are used for lignocellulosic biofuel production? Many different feedstocks can be used for biofuel production. If the process route consists of gasification/pyrolysis followed by a Fisher-Tropsch process, most feedstocks behave similarly. However, if…
