Example Embodiment

[0051] Preparation 1

[0052] Cu (OH) 2 (19.5 g, 0.2 mol) was added to deionized water, stirred evenly; adding tetramethrane (42 g, 0.2 mol) to ethanol and stir evenly. Cu (OH) 2 The molar ratio of tetrapaffene / deionized water / ethanol is 1: 1: 50: 40. Cu (OH) 2 The aqueous solution was slowly introduced into a ethanol solution of a padded benzophenylene, and stirred at room temperature for 24 h. The solid was separated by centrifugation (3500 rpm, 20min), and the solid was washed twice with anhydrous ethanol at 60 ° C. The solid oven was dried at 80 ° C, which demonstrated the resulting product as the HKUST-1 material used in Examples via X-ray powder diffraction. The X-ray powder diffraction test conditions are: using the German Brooke Bruker-AxSD8 X-ray automatic diffractometer, the light source adopts the radio source Cu target Kα radiation, pressure control 30 kV, pipe flow 30mA, continuous scanning, scanning speed of 2 ° / min The scan range is 2 ° ~ 20 °.

Example Embodiment

[0053] Example 1

[0054] Polyvinyl formaldehyde (PVFM, 0.3 g) was added to the DMF organic solvent (6 mL) at 60 ° C heating dissolved stirring mixed, and the HKUST-1 material (2.7 g) was added, and stirred evenly. The MOF-Polymer Mixed Liquid Add (0.1 mL / s) to 100 ml of inverted solvent deionized water / ethanol mixed liquid (volume ratio 1: 2), and the formed composite solvent is quiet in the reverse phase solvent. After the holding was for 1 h, it was soaked 3 times with fresh deionized water (50 mL), and finally the mixture was soaked twice with anhydrous ethanol (50 mL), and the composite material was dried.

Example Embodiment

[0055] Example 2

[0056] Polyvinyl methane (PVFM, 0.45 g) was added to the DMF organic solvent (10 mL) at 70 ° C heating dissolved stirring mixed, and the HKUST-1 material (2.55 g) was added, and stir evenly. The MOF-polymer mixed liquid drop (0.075 ml / s) to 100 ml of inverted solvent deionized water / ethanol mixed liquid (volume ratio 2: 1) was concentrated in an inverted solvent. After retaining 1.5 h, it was soaked 3 times with fresh deionized water (50 mL), and finally used in anhydrous ethanol (50 mL) twice, and the composite material was allowed to dry.

The composite material is stable in framework structure and has high mechanical stability, the pore volume, the pore diameter and the specific surface area of the composite material are large, the light hydrocarbon adsorption capacity is high, the method for preparing the composite material is simple and environmentally friendly, synthesis raw materials are low in price, and large-scale production and application are easy.

Description

technical field [0001] The invention relates to the field of material synthesis, in particular to a composite material with light hydrocarbon adsorption function, a preparation method thereof, and a method and application for removing light hydrocarbons by using the composite material. Background technique [0002] With the country's increasing emphasis on environmental protection, the air pollutant emission standards for refining industries and oil storage depots are becoming more and more stringent. The refining industry and oil storage depots mainly use adsorption technology to recover oil and gas. Commonly used adsorption materials include activated carbon and silica gel. At present, the problem of oil and gas recovery is mainly that small molecular hydrocarbons are difficult to be adsorbed and removed, that is, the activated carbon and silica gel adsorption materials in the existing oil and gas recovery devices have better adsorption effect on large molecular VOCs, but ...
