AI Article Synopsis
- Using biomass-derived compounds as alternative feedstocks in refineries can enhance energy efficiency and promote ecological sustainability.
- A new method was presented to create bio-oil from second-generation biomass through a reaction with acetone, resulting in a product that is more stable and blends well with gasoil compared to traditional bio-oil.
- Catalytic upgrading of this bio-oil with specific zeolites not only produced high-octane gasoline but also improved yield and reduced unwanted compounds when mixed with gasoil, showcasing a beneficial synergy between the two.
Article Abstract
The introduction of biomass-derived compounds as an alternative feed into the refinery structure that already exists can potentially converge energy uses with ecological sustainability. Herein, we present an approach to produce a bio-oil based on carbohydrate-derived isopropylidene ketals obtained by reaction with acetone under acidic conditions directly from second-generation biomass. The obtained bio-oil showed a greater chemical inertness and miscibility with gasoil than typical bio-oil from fast pyrolysis. Catalytic upgrading of the bio-oil over zeolites (USY and Beta) yielded gasoline with a high octane number. Moreover, the co-processing of gasoil and bio-oil improved the gasoline yield and quality compared to pure gasoil and also reduced the amount of oxygenated compounds and coke compared with pure bio-oil, which demonstrates a synergistic effect.
