Considerations for Process Integration and Economic Viability

FIGURE 4.4 Whole slurry enzymatic hydrolysis yields of dilute acid prelreated com stover, with and without feedstock deacetylation. Pretreatment conditions 150°C, 10 minutes, 8 mg Hj S04/g dry biomass, 45% solids in pretreatment reactor prior to steam injection. Enzymatic hydrolysis conditions 25% total solids, no detoxification/conditioning (other than pH adjustment to 4.8), 50°C, 168 hours, No vozymesCelhcCtec2 (20 mg/g cellulose in prelreated slurry) plus Novozymes Cellic Htec2 (20 mg/g cellulose in prelreated slurry). The three bars in each group represent different corn stover varieties as described in Chen et al. (2012).
