Catalytic conversion of furfural extract from lubricating oil extraction unit over the shaped and promoted HY catalysts to valuable petroleum products

Abstract

Catalytic conversion of a furfural extract from the extraction unit of lubricating oil to valuable products was investigated over the shaped HY extrudates using bentonite as binder (HY/bentonite) and zinc and nickel promoted HY/bentonite catalyst (Zn-Ni-HY/bentonite) in a bench scale fixed bed reactor. The catalysts were characterized by XRF, XRD, SEM and nitrogen adsorption-desorption. At 550 °C and LHSV of 9.2 h-1, 7.3 wt% gasoline was yielded over HY/bentonite catalyst, which was significantly increased (ca. 42%) over Zn-Ni-HY/bentonite catalyst. Besides, notably enhanced yield of light and heavy naphtha, kerosene, gas oil and lubricating oil can be distilled from the overall liquid products over Zn-Ni-HY/bentonite catalyst (90.5 wt%) than over HY/bentonite catalyst (77.6 wt%). The obtained petroleum products with the satisfied characteristics can be blended after hydrodesulfurization processing.
