High-performance adsorption desulfurization catalyst as well as preparation method and application thereof

The invention discloses a high-performance adsorption desulfurization catalyst and a preparation method and application thereof, and belongs to the technical field of petrochemical engineering, the high-performance adsorption desulfurization catalyst does not contain an aluminum oxide carrier, a nanoscale IIB group metal oxide is directly used as a carrier, then a VIII group metal oxide component is introduced, and the high-performance adsorption desulfurization catalyst is prepared. According to the present invention, by adding the active metal oxide component and adding the multifunctional auxiliary agent during the preparation process, the diffusion performance of the catalyst is improved, the dispersion degree of the active metal oxide component and the interaction among the components are improved, such that the performance of the synthesized adsorption desulfurization catalyst is excellent, the sulfur content in the sulfur-containing liquid can be reduced to the ppb level, and the environmental protecti
