Embodiment 1
[0036] Utilize the measuring device I measurement analysis process of above-mentioned porous material saturated adsorption capacity as follows:
[0037] Open the valve of the gas extraction chamber 1, reduce the pressure of the precision decompression gauge 2 to below 0.5MPa, dry the gas through the drying column 3, open the first control valve 4, connect the three-way valve D9 to the soap bubble flow meter 11, and adjust the flow rate Open the valve V5 and calibrate the rotameter V7 through the soap bubble flowmeter 11. After the calibration is completed, close the flow regulating valve V5, connect the three-way valve E10 to the soap bubble flowmeter 11, open the flow regulating valve W6, and pass through the soap bubble flowmeter 11 to calibrate the rotameter W8, and close the flow regulating valve W6 after the calibration is completed.
[0038] Take three weighing bottles, weigh them with caps and empty weights M0, record them, then quickly transfer sample 1 into the weighi...
Embodiment 2
[0041] The operation steps are the same as in Example 1, except that the porous material is replaced with Sample 2, and the results are shown in Table 1.
Embodiment 3
[0043] The operation steps are the same as in Example 1, except that the porous material is replaced with Sample 3, and the results are shown in Table 1.
