Embodiment 1
[0022] MOFs material: HKUST-1, adsorption gas: methane CH 4 .
[0023] A certain amount of synthesized HKUST-1 was taken as the MOFs material to be modified and placed in a tube furnace, and N 2 In order to ensure that there is no air residue inside, turn on the electric furnace for heating, so that the temperature in the tube furnace is at 140°C, and 2 A certain amount of pure pyridine was passed into the gas-to-tube furnace, and the constant temperature reaction was maintained at 140°C. The reaction time was 3 hours. The molar ratio of pure pyridine and copper content in MOFs was 1.5:1. 2 The mole percent in gas is 0.1%. After the MOFs reaction tube fumigated by pure pyridine was cooled to below 50 °C, N was introduced into the tube furnace. 2 , to ensure that the N in the tube furnace 2 The air pressure is 0.4MPa, the desorption flow rate is 500mL / min, and the desorption time is 1.5h. After the desorption is completed, the modified MOFs material is obtained and packag...
Embodiment 2
[0029] The improvement of the adsorption performance of modified MOFs materials to benzene under a certain humidity. The material of MOFs is MIL-101.
[0030] A certain amount of synthesized MIL-101 was taken as the MOFs material to be modified and placed in a tube furnace, and N 2 In order to ensure that there is no air residue inside, turn on the electric furnace for heating, so that the temperature in the tube furnace is at 140°C, and 2 A certain amount of pure pyridine was passed into the gas-to-tube furnace, and the constant temperature reaction was maintained at 140 ° C. The reaction time was 3 h. The molar ratio of chromium content in pure pyridine and MOFs was 1.5:1. 2 The molar percentage in gas is 0.5%. After the MOFs reaction tube fumigated by pure pyridine was cooled to below 50 °C, N was introduced into the tube furnace. 2 , to ensure that the N in the tube furnace 2 The air pressure is 0.4MPa, the desorption flow rate is 500mL / min, and the desorption time is ...
