Hybridized organic framework material and preparation method and application thereof

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 ...

AI Technical Summary

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
