Abstract:  
A desulfurization absorbent for hydrocarbon oil, a method and use thereof are provided. Based on the total weight of the adsorbent, the absorbent comprises the following components (1) 1-20% by weight of silicon aluminum molecular sieve with BEA structure, (2) 3-35% by weight of binder selected from at least one of titania, tin dioxide, zirconium dioxide, alumina, (3) 5-40% by weight of silica source, (4) 10-80% by weight of zinc oxide, and (5) 5-30 by weight of metal accelerator metal selected from at least one of cobalt, nickel, iron and manganic, wherein at least 10% by weight of the accelerator metal is in the reduced state. The method for preparing the absorbent comprises contacting the binder, silica source and silicon aluminum molecular sieve with BEA structure with zinc oxideto obtain carrier, contacting the carrier with compounds having the accelerator metal to obtain absorbent precursor, and reducing the precursor to obtain the absorbent. The absorbent has not only better adsorption activity and stability, but also the obvious advantages of increasing the gasoline octane number, when used for desulfurization of hydrocarbon oil.
