The hydrodeoxygenation of raw bio-oil was investigated in a continuousfixed bed reactor over a series ofFeMoP/zeolite catalysts, pursuing a maximized and stable production of phenolics and aromatics. After5 h of reaction, the catalysts reach a pseudosteady activity state. The FeMoP/HZSM-5 catalyst yields thehighest amount of carbon products (53.5 wt%) with the highest selectivity towards aromatics (13.6 wt%,dry basis) and phenolics (12.2 wt%), due to the synergy between the weak acidity of the FeMoP and themild acidity of the HZSM-5 zeolite, which minimizes dehydration and gasification. The MFI frameworkallows the sweeping of coke precursors.
Catalytic cracking of raw bio-oil under FCC unit conditions over different zeolite-based catalysts
Alvaro Ibarra,Idoia Hita,Miren J. Azkoiti,Jose M. Arandes,Javier Bilbao 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.78 No.-
The performance of different zeolite-based catalysts (HY, HZSM-5 and HBeta) on the catalytic cracking ofbio-oil has been explored, using a simulated riser reactor and resembling industrial FCC conditions. Theeffect of the C/O (catalyst/bio-oil) ratio and the zeolite types have been assessed. The level ofdeoxygenation is >61% (increasing with C/O ratio). Total hydrocarbon yield was higher for the HBetacatalyst (56 wt%), while the liquid hydrocarbons yields were relatively similar for all catalysts, obtaininghigher gasoline yields with the HY catalyst (46–55 wt%), and higher LPG yields with the HZSM-5 catalyst(12–14 wt%) due to its higher acidity. The HY zeolite produced more coke (4–7 wt%) given its capacity forretaining coke precursors within its micropores.
