Embodiment 1

[0098] This example is used to illustrate the preparation method of the metal-organic framework molding of the present invention

[0099] (1) Add 6g of trimesic acid into a mixture of 250g of absolute ethanol and 100g of water, stir thoroughly for 20min, then add 11g of copper acetate and 50g of absolute ethanol, and stir thoroughly for 30min. After forming a gel, the above mixture was placed in an ultrasonic reaction for 10 min, and then continued to stir at room temperature for 16 h to obtain a uniform gel-like substance. The obtained product was centrifuged and washed 3 times with absolute ethanol, and dried at 60° C. for 10 h. After drying, HKUST-1 with a smaller crystal size was obtained, and then HKUST-1 was ground into powder.

[0100] (2) Weigh 3g of polyvinyl alcohol 2699 and mix it with 100g of deionized water at 90°C, stir and dissolve to obtain a PVA solution, and then mix it with HKUST-1 powder to form a gel. The mass of HKUST-1 and PVA solution The ratio is 4:1....

Abstract

The invention relates to the field of metal organic frameworks, and discloses a metal organic framework forming body and a preparation method and application thereof. The metal organic framework molded body comprises MOFs and a binder; wherein the amount of the binder is 0.005-1.8 parts by weight per 100 parts by weight of the metal organic framework forming body. The metal organic framework forming body is prepared by adopting a sol-gel method, so that the damage to the MOFs structure caused by granulation, briquetting or tabletting and other modes of a granulator is avoided. The metal organic framework forming body has the advantages of being high in structural retention rate, high in crushing strength, high in sulfur capacity, good in renewability and the like. The adsorbent is wide in application range, is especially suitable for removing sulfides, and has good adsorption and regeneration performances.

Description

technical field [0001] The invention relates to the field of metal-organic frameworks, and discloses a metal-organic framework molding and a preparation method and application thereof. Background technique [0002] With the rapid development of economy and society, the demand for energy and chemical products is increasing day by day. The sulfides contained in crude oil will be transferred to downstream products during processing, which will adversely affect downstream processing and people's production and life. With the increasingly stringent environmental protection regulations around the world, controlling and reducing the sulfur content of products has become an urgent problem to be solved, and has attracted widespread attention from the whole society. [0003] The sulfides in oil products mainly include hydrogen sulfide, mercaptan, sulfide, disulfide, carbonyl sulfide, etc. Among them, organic sulfide is the key to determine the total sulfur content of the product. Co...
