Abstract

Acidic pretreatment of biomass under relatively mild conditions of dilute phosphoric acid and heat results in two streams, the partially hydrolyzed hemicellulosic sugars with organic acids and a lignocellulosic residue. Production of the gaseous fuel, methane, was investigated by comparison of fermentation performance using the standard, continuously stirred tank reactors (CSTR), and up-flow packed bed reactors. The packed bed reactors function equally well at 5. 3 times the dilution rate of the CSTR, require no stirring energy input and offer partial microbial protection against pH changes and oxygen intrusion.
