Problems solved by technology

However, the development cost of imidazole metal-organic framework materials is very high, and its ligand methylimidazole is corrosive and expensive, so it is not conducive to product promotion and application
In addition, the zeolite imidazole framework material falls off during the regeneration process, resulting in a limited service life of the material; moreover, the adsorbent is developed for the mercaptan components in gasoline, and its scope of application is limited, which is not helpful for the increasingly inferior gasoline and diesel desulfurization applications technology

Embodiment 1

[0038] Weigh 5gCu(NO 3 ) 2 ·3H 2 O. Add 3g of 1,4,5,8-naphthalene tetracarboxylic acid into 2000g of acetone aqueous solution, the volume ratio of acetone and water is 1:2, the pH after mixing is 0.73, and put it in an ultrasonic oscillator after airtight, adjust the ultrasonic The frequency is 100KHz, the ultrasonic power is 450W, and it is ultrasonically oscillated at room temperature until a sky blue precipitate appears. Add 0.27 g of soluble starch aqueous solution with a mass concentration of 25 wt % dropwise, keep the ultrasonic conditions unchanged, and continue ultrasonication for 35 min. The obtained mixed solution is suction-filtered, and the filter cake is put into an aqueous acetone solution containing ammonium chloride. The mass ratio of the filter cake to ammonium chloride is 1:1, and the ratio of ammonium chloride to acetone is 1g:120mL. The volume ratio to water is 1:2, and the mechanical stirring is performed at 70 rpm for 60 min. The above solution was su...

Embodiment 2

[0040] The method and raw material are basically the same as in Example 1, except that the copper source is replaced with CuSO of equal quality 4 ·5H 2 O, other reaction conditions and material composition remain unchanged, and hybrid metal-organic framework material B is obtained.

Embodiment 3

[0042] The method and raw material of embodiment 1 are basically the same, the difference is: the volume ratio of acetone and water in the aqueous acetone solution is adjusted to 1:10, and the volume ratio of acetone and water in the aqueous acetone solution containing ammonium chloride is adjusted to 1:10, Other reaction conditions and material composition remain unchanged, and a hybrid metal-organic framework material C is obtained.

Abstract

The invention discloses a hybridized organic framework material preparation method. The method comprises the following steps: 1) adding 1,4,5,8-naphthalene tetracarboxylic acid and a copper source in a solvent, uniformly mixing the materials, performing first ultrasonic treatment, when a precipitate is generated, adding a starch slouble aqueous solution, continuously performing secondary ultrasonic processing; and 2) filtering a mixture through secondary ultrasonic processing, placing a filtered solid in an acetone aqueous solution containing ammonium salt and stirring the materials, then filtering the material, washing the material with water and drying the material to obtain the hybridized organic framework material. The invention also provides the hybridized organic framework material prepared by the method and an application thereof. The hybridized organic framework material has strong thermostability and appropriate pore structure, has more active sites and good space symmetry, and is suitable for an adsorption desulphurization process for fuel oil such as gasoline and diesel oil.

Description

technical field [0001] The invention relates to a hybrid metal organic framework material and its preparation method application, in particular to an organic framework material which can be used for fuel oil adsorption and its preparation method and application. Background technique [0002] With the world's increasing emphasis on environmental protection and the increasingly stringent environmental regulations, the production of low-sulfur and ultra-low-sulfur fuel oil is gradually attracting people's attention. The main forms of sulfide in fuels are mercaptans, sulfides, disulfides and thiophene organic sulfides, especially the thiophenes have a large content and are difficult to remove. Although traditional hydrodesulfurization can effectively remove sulfides such as thiophenes, there are disadvantages such as loss of octane number, high equipment investment and operating costs, so other low-cost fuel oil deep desulfurization technologies are urgently needed. Adsorption ...
