چکیده انگلیسی
This study investigates the effects of Ni impregnation and desilication on HZSM-5 for the hydrodeoxygenation (HDO) of biomass pyrolysis oil. Ni was impregnated in different supporting catalysts, HZSM-5 and desilicated HZSM-5 (DeHZSM-5), and used as catalysts for the catalytic HDO of Geodae-Uksae pyrolyzates. Between HZSM-5(30) and HZSM-5(80), which have different SiO2/Al2O3 ratios (30 and 80), HZSM-5(80) showed the higher desilication efficiency. Ni/DeHZSM-5(80) revealed higher performance on the production of hydrocarbons during the catalytic HDO of Geodae-Uksae pyrolyzates than Ni/HZSM-5(30) because of the increased hydrophobicity, hydrogen reduction efficiency, and mesoporosity of Ni/DeHZSM-5(80) enhanced by the desilication of HZSM-5. Ni/DeHZSM-5(80) also produced larger amounts of esters during the liquid-phase catalytic HDO of Geodae-Uksae pyrolysis oil using supercritical ethanol as a solvent in a high-pressure batch reactor. The two-step catalytic upgrading reaction via the catalytic pyrolysis of Geodae-Uksae over HZSM-5(30) followed by catalytic HDO reaction over Ni/DeHZSM-5(80) enhanced not only the formation of aromatic hydrocarbons and cycloalkanes but also decreased the coke yield on Ni/DeHZSM-5(80).
