- Abstract:
- ... Biomass can be converted into renewable aromatic hydrocarbons through catalytic pyrolysis using ZSM-5 catalysts. Recent studies have found that the mesoporous ZSM-5 catalyst has a higher catalytic efficiency than the conventional microporous catalyst. To further investigate the effect of mesopores in ZSM-5 on the catalytic pyrolysis of biomass, three types of bio-oil model compounds (acetic acid, ...

- Abstract:
- ... Expensive cellulase and complex detoxification procedures increase the cost of biomass lactic acid fermentation. Therefore, it is of great significance to develop a robust method to ferment lactic acid using biomass by avoiding cellulase and detoxification. This study demonstrates the advantage of combining mechanocatalytic P₂O₅ pre-treatment and strain domestication. We show that an enzyme-free m ...

- Abstract:
- ... Peanut husks are agro-industrial waste and represent about 20 wt% of the peanut harvest. This waste product was subjected to fast pyrolysis in a pyroprobe reactor coupled with GC/MS at temperatures ranging from 350 to 600 °C to maximize levoglucosan production. Prior to pyrolysis, the biomass was washed with acetic acid (10 wt%) to remove the alkali and alkaline earth metals. Levoglucosan producti ...

- Abstract:
- ... The large-scale application of bio-oil has been restricted due to its high O content, strong acidity and low heat value. Therefore, the hydrodeoxygenation (HDO) of phenols, acids, and ketones as bio-oil model compounds for hydrocarbon fuel via Ni-based catalysts modified by metal oxides (Al, La and Ga) was investigated. The results showed that the hydrocarbon content was over 70.65% when the mixed ...

However, the recalcitrance of lignin has limited its valorization into value-added products, and it is often burned for heat. The acid-catalyzed organosolv extraction of lignin results in the formation of interunit carbon–carbon bonds, which limit its upgrad ...
