Abstract

The invention discloses a fuel oil desulfurizer and a preparation method thereof. The fuel oil desulfurizer is fullerene carboxylate copper salt loaded on a porous aluminum-based metal oxide, and the loading amount of the fullerene carboxylate copper salt in the porous aluminum-based metal oxide is 10-30 wt%. The porous aluminum-based metal oxide is SiO 2 ‑Al 2 o 3 -CeO 2 A compound composed of a molar ratio of (0.5~1):(2~3):(1~2). The fuel oil desulfurizer provided by the invention has high catalytic activity, good selectivity to sulfur, and high desulfurization depth. When it is applied to the fuel oil oxidation desulfurization process, the desulfurization rate can reach up to 98.7%, and the property is stable and can be recycled. Use, long service life.

Description

technical field [0001] The invention belongs to the technical field of fuel oil processing, and in particular relates to a fuel oil desulfurizer and a preparation method thereof. Background technique [0002] Sulfur in fuel oil mainly exists in the form of organic sulfides, such as mercaptans, thioethers, thiophene and its alkyl derivatives, benzothiophene, dibenzothiophene and their alkyl homologues. The difficulty of fuel oil desulfurization mainly depends on the types of sulfides in the oil. Mercaptans and thioethers are relatively easy to remove, but for valence compounds with aromatic ring properties, such as thiophene and its derivatives, benzothiophene, dibenzothiophene and its alkyl homologues, especially the 4,6 Dibenzothiophene with two alkyl substituents is more difficult to remove. [0003] The current fuel oil desulfurization technology is mainly divided into two categories: hydrodesulfurization technology and non-hydrogenation desulfurization technology. Curr...
