The development of efficient and green pretreatment pathway is of great significance for promoting biofuel production from lignocellulosic waste. The purpose of this work was to evaluate that iron ion-catalyzed hydrogen peroxide pretreatment can be used as an environmentally friendly pretreatment way for bio-jet fuel production using straw.
RESULTS
The effects of iron ion-catalyzed hydrogen peroxide pretreatment (Fe-HP) on the enzymatic hydrolysis, fermentation and bio-jet fuel production using straw were investigated. It was found that the iron ion-catalyzed hydrogen peroxide pretreatment significantly improved the enzymatic hydrolysis and fermentation efficiency of straw biomass. Subsequently, the directional catalytic transformation of straw-derived fermentation broth to bio-jet fuels was achieved using a dual functional catalyst (HSAPO34/NiHBET). High conversion (94.9%) and good jet-fuel selectivity (77.3%) were obtained in the conversion process of straw. On account of the biomass characterization and the analysis of reactive oxygen species during the Fe-HP pretreatment, the role and mechanism of the Fe-HP pretreatment was addressed.
