Abstract

Microwave irradiation is one of pretreatment technologies in the biorefinery area. In this paper, we carried out a comparative study of the two distinct bio-based materials such as pine and eucalyptus as feedstocks subjected to a combination treatment of microwave irradiation and chemical micronization at a given reaction severity. The micronized residues were characterized in terms of reaction yields, residual lignin contents, sugar compositions, crystallinity, and dissolution behaviors on a aqueous Urea/NaOH solution. It was found that hardwood under the combination treatment of microwave and chemical micronization is more sensitive than softwood, resulted to a rapid decrease in yields, and residual lignin contents. The pronounced losses of hemicellulose and lignin in the hardwood made easily soluble in the aqueous Urea/NaOH solution.
