The invention discloses a regular carrier catalyst with a desulfurization effect as well as preparation and application thereof. The regular carrier catalyst comprises a regular carrier and an activecoating attached to the surface of the regular carrier, wherein the active
coating comprises a matrix containing IIA and IIB group
metal oxides and a modified
metal film attached to the outer surfaceof the matrix, the modified
metal film comprises a modified metal, and the modified metal is one or more of Fe, Co, Ni, Mn, Ti, Zr, V, Ge, Pb, Sn, Sb and Bi. The preparation method comprises the following steps: forming a mixture from
metal powder, a hydroxyl-containing
solvent and a surfactant, then treating the mixture under ultrasonic
waves to obtain a
mixed solution after the ultrasonic treatment; separating the
mixed solution after ultrasonic treatment to obtain suspension; contacting the suspension with matrix particles, carrying out
freeze drying to obtain matrix particles containing amodified metal film, and
coating the regular carrier with the matrix particles containing the modified metal film to obtain the regular carrier catalyst. The catalyst is used for
hydrocarbon hydro-desulfurization, has high desulfurization activity and good stability, and can reduce the
octane number loss of
gasoline.
