High temperature acid hydrolysis of biomass using an engineering - scale plug flow reactor. Results of low testing solids

An engineering-scale experiment at the Solar Energy Research Institute investigating dilute acid hydrolysis of lignocellulosic biomass using a 3.8-cm (1.5-in) diameter plug flow to 900 kg/h (2000 lb/h) at 200-260 degrees and 4-20 seconds residence time. Initial experiments operated with 10 weight percent solids slurries to verify that yields obtained in bench-scale experiments could be maintained at a larger scale. The results of these tests can serve as a baseline for research addressing prehydrolysis of the slurry, high solids pumping, pretreatment requirements, and fermentability.
