Example Embodiment

[0037] Example 1

[0038] Weigh 5gCu(NO 3 ) 2 ·3H 2 O, 3g 1,4,5,8-naphthalenetetracarboxylic acid is added to 2000g acetone aqueous solution, the volume ratio of acetone and water is 1:2, the pH after mixing is 0.73, sealed and placed in an ultrasonic oscillator to adjust the ultrasonic The frequency is 100KHz, the ultrasonic power is 450W, and it is ultrasonically vibrated at room temperature until sky blue precipitates appear. 0.27 g of a soluble starch aqueous solution with a mass concentration of 25 wt% was added dropwise, maintaining the ultrasonic conditions unchanged, and continuing the ultrasonic for 35 minutes. The obtained mixed solution was filtered by suction, and the filter cake was placed in an aqueous acetone solution containing ammonium chloride. The mass ratio of the filter cake to ammonium chloride was 1:1, and the ratio of ammonium chloride to acetone was 1g:120mL. The volume ratio to water is 1:2, and mechanical stirring is performed at 70 rpm for 60 minutes...

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 ...
