Description

Technical Field

[0001] The invention relates to a method for preparing a sulfidation type hydrogenation catalyst. Background Art

[0002] The petroleum fraction hydrogenation process is the key technology for producing clean oil products. Among them, high-performance hydrogenation catalysts are the key to hydrogenation technology.

[0003] Traditional petroleum fraction hydrogenation catalysts are prepared by loading active components such as cobalt, nickel, tungsten and molybdenum on porous carrier materials to form supported solid catalysts. Among them, active components such as cobalt, nickel, tungsten and molybdenum exist in the form of oxides. In actual use, a sulfiding agent is used to convert the active components on the petroleum fraction hydrogenation catalyst into sulfide forms of cobalt, nickel, tungsten and molybdenum to obtain ideal hydrogenation activity and stability. Therefore, petroleum fraction hydrogenation catalysts need to be sulfurized before use.

[0004] There are two methods for sulfurization of hydrogenation catalysts: in-situ sulfurization and ex-situ sulfurization. In-situ sulfurization is to load the oxidized catalyst into the hydrogenation reactor, and introduce hydrogen and sulfurizing agent into the reactor during the heating process for pre-sulfurization. The disadvantages of this method are: special pre-sulfurization equipment is required, the sulfurization time is long, the sulfurization cost is high, the sulfurizing agent is highly toxic and flammable, and it is easy to cause pollution to people and the environment.

[0005] The ex-situ sulfidation method is to transfer the pre-sulfidation of the catalyst to a special sulfidation reaction device or the prepared catalyst is already a sulfided catalyst, so that the catalyst can be loaded into the hydrogenation reactor and used without further sulfidation. It has become the development trend of hydrogenation catalyst preparation technology in recent years. At present, the ex-situ sulfidation technology of hydrogenation catalysts with more industrial applications mainly consists of two technical routes:

[0006] (1) The first technical route is to complete the presulfurization of the catalyst in the presence of hydrogen and hydrogen sulfide or an easily decomposable organic sulfiding agent in a special presulfurization device, and then passivate it with oxygen-containing gas to produce a non-self-igniting presulfurized hydrogenation catalyst;

[0007] (2) The second technical route is to first introduce the sulfiding agent (composed of petroleum solvents containing olefin components, elemental sulfur, vegetable oil, organic sulfides, organic polysulfides, sulfones, sulfoxides and vulcanization accelerators) into the voids of the oxidized hydrogenation catalyst by sublimation, melting or impregnation, and then pre-sulfurize the catalyst partly by heating treatment in the presence of nitrogen. Finally, the catalyst is loaded into the hydrogenation reactor and the pre-sulfurization of the catalyst is completed during the start-up heating process and in the presence of hydrogen.

[0008] U.S. Patent No. 5,958,816 proposes the use of a fluidized bed process, in which a hydrogenation catalyst is sulfurized with H2 / H2S gas in a dedicated presulfurization reactor, and then passivated with oxygen-containing gas or air. The catalyst is directly loaded into the reactor and started in use. This patent solves the problems of high temperature and acidic water release during the sulfurization process, but the process is complicated and the processing cost is high. Sulfate is generated during the air passivation process and remains on the catalyst, affecting the service life of the catalyst.

[0009] Chinese patent application 91101805.7 discloses a method for incorporating sulfur into the pores of a hydrocarbon treatment catalyst, which is characterized by: first treating the catalyst with a solvent-diluted sulfiding agent, and then sulfiding the catalyst in the presence of water vapor at a temperature above 250°C. The sulfiding agent used is composed of elemental sulfur and an organic sulfur compound that easily decomposes hydrogen sulfide in the presence of hydrogen, and the solvent used is a solvent oil containing an olefin fraction or a vegetable oil. Chinese patent application 85107953 discloses a method for treating a hydrogenation catalyst, which mainly includes first impregnating the hydrogenation catalyst with elemental sulfur dissolved and diluted with a petroleum solvent and a variety of organic polysulfides at 50 to 150°C, then treating the catalyst at a temperature below 275°C in a hydrogen-free atmosphere, sulfiding the active metal oxide, and finally activating the catalyst at a temperature above 275°C in the presence of hydrogen. U.S. Patent No. 6365542 discloses a method for presulfiding a hydrogenation catalyst outside the device, which is characterized by first treating the oil containing elemental sulfur and olefins with nitrogen at a temperature of 100 to 300°C.

[0010] U.S. Patent No. 5,985,787 discloses a presulfurization method for a hydrogenation catalyst, which is characterized in that the vulcanizing agent is an olefin-containing oil, vegetable oil, organic sulfide, organic polysulfide, elemental sulfur, etc. diluted with a solvent, wherein there must be both sulfides with a decomposition temperature below 220°C and sulfides with a decomposition temperature above 220°C. U.S. Patent No. 5,681,782 improves the previous catalyst presulfurization technology by adding an oxygen-containing organic compound during the addition of the sulfide. Chinese Patent Application No. 98801896.9 discloses a vulcanizing agent for the ex-situ vulcanization of a hydrogenation catalyst, which is mainly composed of tertiary mercaptans of C4 to C16 and is used in combination with H2S, CS2, primary or secondary mercaptans, organic polysulfides, thiophene and its derivatives, sulfoxides, sulfones, cyclopentane, etc. Chinese patent application 00100400.X discloses an ex-situ presulfurization method for a hydrogenation catalyst, which is characterized in that an olefin-containing component, elemental sulfur and an additive are first mixed, heated at 100 to 220°C for more than 0.5 hour, and then the catalyst is impregnated with the obtained product and treated with nitrogen at a temperature of 100 to 300°C for more than 1 hour.

[0011] The patented technologies reported above are all ex-situ presulfurization technologies. Compared with in-situ sulfidation, they have the advantages of high catalyst activity, saving start-up time, simplifying start-up steps, and less pollution to people and the environment. However, the ex-situ presulfurization is the same as the in-situ presulfurization. The presulfurization process is carried out under the action of hydrogen. The oxidized catalyst may undergo hydrogenolysis reaction, and the binding force between the active component and the carrier is often too strong, so that the hydrogenation catalyst cannot be completely sulfided, resulting in the catalyst activity cannot be further improved. The catalyst is presulfurized in an oxidized state before use, which increases the production steps of the catalyst and the production cost, directly affecting the economic efficiency of the process.

[0012] In addition, another new preparation method of sulfidation type hydrogenation catalyst has been reported in recent years, that is, using Mo or W sulfide precursor to directly prepare sulfidation type hydrogenation catalyst. Chinese patent CN1569331 discloses a modified cobalt-molybdenum-based sulfide catalyst and its preparation method, by preparing ammonium thiomolybdate solution, coprecipitating molybdenum, cobalt and a third transition metal component, and roasting under nitrogen protection to obtain a black powder catalyst. The disadvantage of this method is that it can only prepare powdered catalysts and cannot be used in large-scale fixed bed hydrogenation equipment; waste liquid is generated in the preparation process, there are environmental problems, and the preparation cost is high.

[0013] Chinese patent CN200410039449.5 discloses that the precursors of Group IVB metals Mo and W are introduced into the voids of the hydrogenation catalyst carrier by using soluble thiomolybdate and thiotungstate solutions, and converted into sulfides of Mo and W by heating treatment in nitrogen, and then a soluble salt solution of Co or Ni is introduced, and converted into sulfides of Co or Ni by heating treatment in nitrogen, thereby preparing a sulfide-type hydrogenation catalyst loaded with metal sulfides. Chinese patent CN200810228363.5 uses an impregnation solution to impregnate the required catalyst carrier, and then obtains a sulfide-type hydrogenation catalyst by drying and heat treatment, characterized in that the impregnation solution contains a sulfide precursor of metal Mo or W, and also contains a complex of Ni or Co inorganic salt; the heat treatment process is to treat at 200-350°C for 1-10 hours; and drying and heat treatment do not require nitrogen protection.
