Hydrocarbon oil desulfurization adsorbing agent, production and use thereof |
摘要 |
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. |

1. A process for producing a desulfurization adsorbing agent for hydrocarbon oil, comprising:
(1) contacting at least one binder selected from the group consisting of titanium dioxide, stannic oxide, zirconium oxide and alumina with a silica source, a Si—Al molecular sieve having a BEA structure and zinc oxide, to obtain a carrier, (2) contacting the carrier with a promoter metal-containing compound, to obtain a precursor of the adsorbing agent, and (3) under a condition sufficient to present at least 10 wt % of the promoter metal in a reduced valence state, treating the precursor of the adsorbing agent, to obtain the desulfurization adsorbing agent for hydrocarbon oil, wherein the step (1) further comprises: (1a) mixing the binder or a binder precursor with an acid to form a slurry, and (1b) mixing the slurry, the silica source, the Si—Al molecular sieve having a BEA structure and zinc oxide to form a mixture and subject the mixture to molding, drying, and calcination to obtain the carrier, wherein the desulfurization adsorbing agent comprises: 1) a Si—Al molecular sieve having a BEA structure: 2) at least one binder selected from the group consisting of titanium dioxide, stannic oxide, zirconium oxide and alumina; 3) a silica source; 4) zinc oxide; and 5) at least one promoter metal selected from the group consisting of cobalt, nickel, iron and manganese, based on the metal, wherein at least 10 wt % of the promoter metal is present in a reduced valence state, and wherein the Si—Al molecular sieve is in an amount of 2-15 wt %, the binder is in an amount of 5-25 wt %, the silica source is in an amount of 10-30 wt %, zinc oxide is in an amount of 25-70 wt %, and the promoter metal is in an amount of 8-25 wt %, all based on a total weight of the desulfurization absorbing agent. |
