Embodiment 1

[0025] Weigh 28.2g of powdery active zinc oxide, 27.9g of powdery active nickel oxide, 32.0g of diatomaceous earth and 11.9g of high-alumina cement, then add 1-2g of graphite, mix well, and press it into a cylinder of ф5×4-6 .

Embodiment 2

[0027] Weigh 36.9g of powdery active zinc oxide, 18.1g of powdery active nickel oxide, 18.5g of pentonite and 25.5g of zeolite, then add 1-2g of graphite, mix evenly, and press into a cylindrical shape of ф5×4-6.

Embodiment 3

[0029] Weigh 52.7g of zinc nitrate, add it to a 500ml beaker, add 200ml of water, and stir to dissolve it completely. While stirring, adjust the pH value to about 6.5 with 1.0M NaOH aqueous solution, and then adjust the pH value with 0.1-0.2M ammonia solution to 7.0, place the precipitate for 24 hours, filter, wash the precipitate with water several times until there is no sodium ion in the filtrate, dry and grind the filter cake, add 42.3g powdered activated nickel oxide, 30.0g clay and 14.0g ordinary cement , then add 1~2g of graphite, mix well, and press it into a cylindrical shape of ф5×4~6.

Abstract

The invention relates to a desulfurizing agent for reforming stock oil and a preparation method thereof, in particular to the desulfurizing agent used for desorbing sulfides in the reforming stock oilsuch as H2S and the like. The desulfurizing agent is characterized by consisting of 10%-40% of ZnO, 15%-22% of NiO, 10%-17% of Al2O3, 5%-22% of SiO2 and the balance inevitable impurities. The desulfurizing agent takes zinc and nickel as active components and bentonite (or diatomite, or white clay, or zeolite, or high-alumina cement and or common cement) as a carrier, and active components thereofare directly present in the form of oxides of zinc and nickel or oxides transformed by corresponding carbonate (basic carbonate) and nitrate. In the invention, the desulfurizing agent has enlarged raw material range, thus effectively reducing raw material cost, simplifying production process of the desulfurizing agent, lowering production cost, improving strength to more than twice, and prolonging service life of the desulfurizing agent.

Description

technical field [0001] A reforming raw material oil desulfurizer and a preparation method thereof, relating to a method for removing H from reforming raw material oil 2 Desulfurization agent used for sulfide such as S. Background technique [0002] H 2 S and other sulfides. If these sulfides are not removed, they will corrode pipelines and equipment and cause subsequent catalyst poisoning or even deactivation, so they must be removed. At present, the existing reformed raw oil desulfurizers on the market use copper and nickel as active components and kaolin as a carrier to reduce the sulfur content in raw oil to below 0.5PPM (patent number: 87103035), but the desulfurizer There are disadvantages such as high cost, complex production process, low technical indicators (such as lateral pressure strength), and short service life. Contents of the invention [0003] The purpose of the present invention is to provide a reformed raw oil desulfurizer and a preparation method ther...
