Hydrocarbon oil desulfurization adsorbing agent, production and use thereof

Abstract

This disclosure provides an adsorbing agent which, on the basis of the total weight of the adsorbing agent, comprises the following components: 1) a Si—Al molecular sieve having a BEA structure, in an amount of 1-20 wt %, 2) at least one binder selected from the group consisting of titanium dioxide, stannic oxide, zirconium oxide and alumina, in an amount of 3-35 wt %, 3) a silica source, in an amount of 5-40 wt %, 4) zinc oxide, in an amount of 10-80 wt %, and 5) at least one promoter metal selected from the group consisting of cobalt, nickel, iron and manganese, based on the metal, in an amount of 5-30 wt %, wherein at least 10 wt % of the promoter metal is present in a reduced valence state. The adsorbing agent exhibits improved activity and stability, and at the same time, is capable of significantly improving the octane number of the product gasoline.
