Method for preparing alumina—zinc oxide—nickel oxide composite for desulfurization

摘要

Alumina/NiO/ZnO and Alumina/ZnO are synthesized via a novel modified hydrothermal method and investigated for the desulfurization activities. Sulfur compounds such as thiophene, benzothiophene (BT) and dibenzothiophene (DBT) are tested for their removal from model diesel fuel. The prepared composite materials were examined by the means of N2-adsorption, X-ray diffraction and Fourier transform infrared spectroscopy.

1. A method for obtaining a metal-oxide/NiO/ZnO material, comprising:
dispersing a metal-oxide in a solvent to form a mixed solution; dissolving a zinc compound and a nickel compound in an aqueous solution to form a second mixed solution; mixing the first and second mixed solutions to form a mixture; sonicating the mixture; heating the mixture; cooling and filtering the mixture to obtain the desired material; drying the mixture; and calcining the mixture to form a metal-oxide/NiO/ZnO material having a surface area of about 10-15 m2/g, a pore volume of about 0.1-0.8 cm3/g, and an adsorption average pore width of about 500-600 Å.
