Table 2 Average pore size and BET surface area of soda-extracted straw at different NaOH loadings
From: Reinforcement of the bio-gas conversion from pyrolysis of wheat straw by hot caustic pre-extraction
Extracted NaOH loading (w/w dry straw), % | Average pore size (nm) | Cumulative pore volume (cm3/g) | BET specific surface area (m2/g) |

Unextracted | 13.90 | 0.01 | 0.47 |
6 | 15.07 | 0.02 | 0.48 |
14 | 15.57 | 0.03 | 0.67 |
22 | 14.43 | 0.02 | 0.61 |
