Description
Technical Field
The invention belongs to the technical field of gas separation, and particularly relates to a method for preparing a ZIF-67 adsorbent by a steam-assisted method and application of the ZIF-67 adsorbent in cyclohexane adsorption.
Background
In the past decades, global warming due to cyclohexane emissions has posed a serious threat to the human and natural environment, creating worldwide concern over how to reduce CO2Emissions are one of the current research hotspots. The use of solid adsorbents such as zeolite for combustion capture is considered a promising cyclohexane capture technology because it saves energy and cost. However, the use of solid adsorbents is limited because the adsorption process is typically affected by operating temperature, water vapor, and other factors. The development of a regenerable adsorbent material with high selectivity, adsorption capacity and adsorption-desorption rate is crucial to the adsorption process. In order to overcome this problem, research on materials having excellent gas separation performance should be conducted.
Zeolite imidazole framework materials (ZIFs) are novel porous materials composed of imidazolium salts linked to coordinated divalent cations and have exceptionally high thermal and chemical stability. Compared with porous oxides, the ZIFs material has an abnormally developed pore structure, a specific surface area and a special space topological structure, and has great advantages and application prospects in the aspect of adsorption. ZIF-67 is well known as a typical porous material with albite (SOD) topology that can be boiled in water and other solvents without damaging the structure.
ZIFs materials are generally synthesized by a solvothermal method, in a solvothermal reaction, a precursor is dissolved in a non-aqueous solvent, and the reaction is carried out under a liquid phase or supercritical condition. The disadvantages of the solvothermal process are the slower reaction, the higher solvent consumption and the higher waste liquid generation. Therefore, a method for preparing a ZIF-67 adsorbent with less solvent consumption and high environmental friendliness is required.
CN201811617674.0 discloses an ionic copolymer composite adsorbent, a preparation method and application thereof. Preparing a porous ionic copolymer by copolymerizing an ionic liquid monomer and a cross-linking agent divinylbenzene; and loading the metal organic framework material on the surface of the porous ionic copolymer in an in-situ growth mode to obtain the porous ionic copolymer composite adsorbent. The prepared adsorbent has both micropore and mesoporous structures, and has higher porosity and abundant CO2Chemisorbed basic functional groups exhibiting high CO2Adsorption capacity and faster CO2Adsorption diffusion rate, CO at low pressure2The adsorption capacity is obviously improved, and the adsorption capacity is not obviously reduced after repeated use. The composite adsorbent has the advantages of multistage pore structure, and is favorable for gas diffusion and adsorption. However, the disadvantages are that the preparation process is complicated, the cost of ionic liquid in the raw material for synthesis is expensive, and the synthesis yield of in-situ growth is low, which limits the industrial application of the ionic liquid.
CN201610350526.1 discloses a ZIF (Co) -based2+) Preparation and application of novel microporous spheres of the metal organic framework material. The preparation of the microsphere takes a carboxyl functionalized polymer macroporous microsphere as a substrate, and ZIF (Co) is synthesized on the surface of the microsphere by an in-situ growth method2+) And (3) forming the metal organic framework material to obtain the novel microporous ball with the microporous structure. Which comprises the following steps: dispersing a proper amount of carboxylated macroporous microspheres in a divalent cobalt salt solution for a certain time, adding an imidazole solution into the dispersion, fully reacting for a certain time, and then carrying out low-speed centrifugation to collect modified microspheres; repeatedly soaking, washing and vacuum drying to obtain the novel microporous ball. The novel microporous ball can be used as an adsorbent to efficiently and quickly adsorb dyes in water. The invention proposesThe preparation method of the novel microsphere can further design and prepare the microsphere based on other metal organic framework materials so as to optimize the adsorption performance by combining the microporous structures of different types of metal organic framework materials. The disadvantages of this process are long time consumption, high solvent consumption and low synthesis yield for in situ growth.
