Summary of maximal glucose yields obtained after Ionosolv pretreatment of for agroresidues at 170°C using [TEA][HSO4], a water content of 20 wt% and a biomass to solvent ratio of 1:10 g/g.
| Feedstock | Optimal pretreatment condition | Saccharification yielda | Increase in saccharification yieldb | |
|---|---|---|---|---|
| With air drying (%) | Without air drying (%) | |||
| Wheat straw | 170°C, 30 min | 80.5 ± 0.8 | 86.5 ± 1.9 | 5.6 |
| Rice straw | 170°C, 30 min | 68.3 ± 0.5 | 88.8 ± 0.2 | 3.4 |
| Rice husk | 170°C, 45 min | 58.8 ± 1.5 | 73.0 ± 4.3 | 30.4 |
| Sugarcane bagasse | 170°C, 45 min | 78.4 ± 2.1 | 89.4 ± 5.5 | 8.1 |
a
Calculated as a percentage of glucan content in untreated biomass.
b
Calculated as ratio of wet pulp sugar yield compared to sugar yield for untreated biomass.
