Reactivity of sulfur compounds in FCC decant oils for hydrodesulfurization over CoMoS2/Al2O3 catalysts

CoMoS 2 /Al 2 O 3 catalysts prepared by adding citric acid (CA) were synthesized and applied tor hydrodesulfurization (HDS) of fluid-catalytic cracking decant-oils (FCC-DO). The HDS of FCC-DO was carried out in an autoclave batch reactor at 653 K and 9.4 MPa H 2 . The structural properties of the ca...

Summary:CoMoS 2 /Al 2 O 3 catalysts prepared by adding citric acid (CA) were synthesized and applied tor hydrodesulfurization (HDS) of fluid-catalytic cracking decant-oils (FCC-DO). The HDS of FCC-DO was carried out in an autoclave batch reactor at 653 K and 9.4 MPa H 2 . The structural properties of the catalysts were characterized by N 2 physisorption, X-ray absorption fine structure spectroscopy (XAFS), and transmission electron microscopy (TEM). The S compounds in FCC-DO have been classified into three groups in terms of the reactivity of HDS. The Co K-edge XANES analysis confirmed the formation of the Co-Mo-S phase with the addition of CA, contributing to better activity in the HDS of FCC-DO.
