Integration of autohydrolysis and organosolv process for recovery of lignin from corncob

Abstract

[Excerpt] Lignocelluloses, such as hardwood, softwood and agricultural residues, are low cost feedstocks mainly composed by cellulose, hemicellulose and lignin. Lignin is the third most abundant naturally synthesized polymer. It presents an amorphous polyphenolic structure, which can be used for the development of bio-based materials and chemicals. However, the bioconversion of renewable lignocelluloses to valueadded products requires their fractionation through pretreatment technologies [1,2]. [...]
