Reformed raw oil desulfurizing agent and preparation method thereof

Abstract

The invention provides reformed raw oil desulfurizing agent, which is prepared by following raw materials by weight percent: 10 to 40 percent of copper oxide (CuO), 15 to 30 percent of nickel oxide (NiO), 5 to 25 percent of zinc oxide (ZnO) and balance of carriers; and the carrier is aluminate cement or / and ordinary prtland cement. The invention also provides a preparation method of the reformed raw oil desulfurizing agent, and the method comprises follwing steps that A, CuO, NiO, ZnO and carriers are weighed according to the mass percent and are uniformly mixed to obtain mixture; B, after deionized water with a given quantity is placed into the mixture, the mixture is mixed and rolled and is extruded into bars; and C, and the reformed raw oil desulfurizing agent can be obtained through drying and roasting. Raw materials of the reformed raw oil desulfurizing agent is widely sourced, the preparation process is simple, and the production cost is low; and the desulfurizing efficiency of the reformed raw oil desulfurizing agent is high, the radial pressure and crush resistance is high, the service life is long, and the desulfurizing agent is suitable for the industrialized mass production.

Description

technical field [0001] The invention belongs to the technical field of desulfurization of oil products, and in particular relates to a reforming raw material oil desulfurizer and a preparation method thereof. Background technique [0002] At present, the catalytic reforming of raw oils such as straight-run naphtha is a common method for industrial production of aromatics, high-octane gasoline and hydrogen used in hydrogenation processes. [0003] Early catalytic reforming processes used single platinum catalysts, but with poor results. In order to increase the yield of aromatics, gasoline octane number, hydrogen production, and extend the operating cycle, a series of high-efficiency bimetallic reforming catalysts have been developed over the years, such as platinum-rhenium reforming catalysts with equal platinum-rhenium ratio and high platinum-rhenium ratio. However, the trace amount of hydrogen sulfide and organic sulfur contained in the reforming feed oil has a great infl...

AI Technical Summary

Problems solved by technology

However, the proportion of precious metals in the existing desulfurizers is relatively high, resulting in high production costs. At the same time, there are disadvantages such as complex production processes, low radial crushing strength, and short service life.

[0005] So far, no reforming raw material oil desulfurizer with CuO, NiO and ZnO as ternary active components and aluminate cement or / and ordinary Portland cement as the carrier has been reported.
