Sequential acid and alkaline hydrothermal pretreatment using sulfuric acid and lime were evaluated to recover hexose and pentose from biomass. Process performance was optimized in terms of catalyst concentration, retention time and temperature using Response Surface Methodology. Medium operational conditions in the acid stage and harsh conditions in the alkaline stage were desirable with optimal performance at 0.73 wt% H2SO4, 150 oC, 6.1 min in the first stage, and 0.024 g lime/g biomass, 202… CONTINUE READING
