Corn stover pretreatment by inorganic salts and its effects on hemicellulose and cellulose degradation

Inorganic salts, NaCl, KCl, CaCl 2, MgCl 2, FeCl 2, FeSO 4, FeCl 3, and Fe 2(SO 4) 3, were studied as catalysts for the degradation of hemicellulose in corn stover. FeCl 3 significantly increased the hemicellulose degradation in aqueous solutions heated between 140 and 200 °C with high xylose recove...

Zusammenfassung:	Inorganic salts, NaCl, KCl, CaCl 2, MgCl 2, FeCl 2, FeSO 4, FeCl 3, and Fe 2(SO 4) 3, were studied as catalysts for the degradation of hemicellulose in corn stover. FeCl 3 significantly increased the hemicellulose degradation in aqueous solutions heated between 140 and 200 °C with high xylose recovery and low cellulose removal, amounting to ∼90% and
