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
Many different feedstocks are used in the production of biofuels. Lignocellulosic biofuels are those produced by feedstocks that contain lignocellulosic biomass, composed of cellulose, hemicellulose, and lignin. These will normally be non-foods materials that are…
