Impeller Selection for Lignocellulosic Hydrolysis Reactors

Impeller Selection for Lignocellulosic Hydrolysis Reactors

March 16, 2017 |

By Gregory T. Benz, Lee Enterprises Consulting Special to The Digest Lignocellulosic slurries at high solids concentrations (10-30%) can be quite viscous. The author has seen some where the viscosity at a shear rate of 1/s is higher than 400,000 cP. Conventional agitator impeller selection guidelines would lead one to use helical ribbon impellers (figure […]

Modified silica-based cellular matrices lead to exceptional yields

Modified silica-based cellular matrices lead to exceptional yields

July 5, 2011 |

In France, researchers at the Centre de Recherches Paul Pascal have developed modified silica-based cellular matrices that make it possible to confine lipases (triglyceride hydrolases used as catalysts) in order to obtain exceptional yields for hydrolysis, esterification and transesterification reactions in biodiesel production. Their work had also shown that unpurified enzymes could be used in […]
