Hydrodeoxygenation of Anisole and Benzaldehyde Over Bifunctional CoMo/USY Catalyst

Abstract

Hydrodeoxygenation (HDO) of anisole and Benzaldehyde over bifunctional zeolite USY (ultra-stable Y) supported CoMo catalysts has been studied. The catalyst consisted of metals that Co and Mo were loaded at three different sequences; Co loaded first (Co-Mo/USY), Mo loaded first (Mo-Co/USY), and simultaneously loaded (CoMo/USY). The experiments were conducted in a flow reactor within a temperature of 350 °C for an hour. The oxygen-free products from the HDO process were benzene and toluene compounds. CoMo/USY catalyst exhibited the best catalytic activity of anisole towards the total production of aromatic hydrocarbons yield by 9.17%. It was also found that Mo-Co/USY catalyst exhibited the best catalytic activity of Benzaldehyde with aromatic hydrocarbons yield by 10.46%.
