Sulfite-catalyzed acid pretreatment to overcome the inherent recalcitrance of biomass offers a significant advantage in terms obtaining high glucose conversion. However, residual lignin after enzymatic hydrolysis has not been fully exploited. Herein, this study introduced joint approach using sulfite-catalyzed (SPROL) and pyrolysis upgrade tobacco stalk produce fermentable sugar, resulting is used bio-oil bio-char. The results suggest that SPROL pretreated yields cellulose-based selectivity 75.9% with 15 FPU/g substrate enzyme dosage at 50 °C 72 h enzymolysis. Lignin characterization reveals sulfonation occurred during pretreatment, as sulfonating agent increased, thermal stability residue decreased. After sample 600 for 30 min, approximately 22%, 33%, 45% undergoes conversion into bio-oil, bio-char, gas products, respectively. analysis demonstrated acetic most abundant identified GC-MS component around 69.91% optimal condition, which implied it could be value when utilized pyroligneous acid. This research provides synthetic SPORL technique process commercial utilization agricultural waste value-added products.

Uncovering the structure of lignin from biorefinery has an important effect on catalytic depolymerization and production bioenergy. In this study, two lignins were isolated tobacco stalks via alkaline deep eutectic solvent (DES) catalyzed delignification processes, heterogeneity structural characteristics elucidated by gel permeation chromatography, 2D-HSQC, FT-IR, etc., to understand relationship between thermal lignin. It was found that presented various components, in which predominant interunit linkages black liquor are β-O-4 β-β linkages, disappeared DES treatment. exhibited lower molecular weights yields than Thermogravimetric analysis fixed-bed pyrolysis also performed investigate behavior. The results show approach can improve bio-oil highlight potential as a promising feedstock process. This work provides valuable example conversion into products.
