Conférence du Pr. Marcelo PEREIRA portant sur "Sweetening the refinery: gasoline from biomass coupled with CO2 recycle"

Le 28 novembre 2014
De 10h30 à 12h00

Le Pr. Marcelo Maciel PEREIRA , de l’Université Fédérale de Rio de Janeiro, donnera une conférence le 28 novembre 2014 à 10h30 en salle de conférences de l'ICPEES  (bâtiment R3 Niveau1) ayant pour titre  "Sweetening the refinery: gasoline from biomass coupled with COrecycle".

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. Finally the coke formed in the spent catalyst was suitable to be regenerated in the presence of CO2 rich atmosphere. The possibility of performing this step in the presence of CO2/O2, instead of air can remarkably mitigate greenhouse gas emissions and simultaneously produce a huge amount of CO for sequential uses.
