Embodiment 1-3

[0047] Load a certain amount of chemicals into the vial, then add a certain amount of water, and mix thoroughly, for example, mix 5.0g APTEOS with 5.0g water to obtain a 50% aqueous solution. Three solutions as shown in Table 1 were prepared.

[0048] Table 1

[0049]

[0050] Glass wool paper was used as the substrate for Examples 1-3. The substrate (the mass of which was measured before applying the sorbent) was immersed in the solution for 10-15 seconds, and then dried at room temperature for several hours to overnight (the mass of which was measured again). The weight gain (percent weight gain of the solid adsorbent containing moisture) was derived from the difference in mass (percent weight gain for each test sample was approximately 65%).

[0051] In humidified CO with little back pressure 2 atmosphere, conduct CO on the resulting sample 2 Capture capacity test. The results of the adsorption rate A, desorption rate B, and estimated water content C for the first c...

Embodiment 4

[0061] The silica / PEI mixed adsorbent solution prepared in the above manner was distributed on the high-porosity honeycomb substrate. The amount of solid adsorbent material on the substrate is about 10% by weight. Use contains 9.2% CO 2 , 5.5%H 2 O and a margin of N 2 gas flow, the sample CO 2 Capture capacity was tested. The adsorption rate was tested at room temperature. Four cycles of different adsorption times were measured from 10 minutes to 20 minutes. No water adsorption peak was detected, but water desorption curves were observed at temperatures below 100 °C. During these four cycles, CO 2 The capture capacity is stable. CO occurs within 3 minutes 2 adsorption. An increase in sample temperature was observed during adsorption. The CO of this sample 2 The capture efficiency is about 35%.

[0062] Then, the sample was heated to 120°C to make the CO 2 desorption. Two desorption peaks were observed, as Figure 4 shown in . A peak at approximately 38 °C to 4...

Abstract

Disclosed is an adsorbent article comprising a substrate having porous channel walls defining open channels, and an organic-inorganic hybrid adsorbent material distributed on the surface of the porous channel walls; wherein the adsorbent material is composed of amino-functionalized alkoxy Silanes and polyamines are obtained, and CO2 adsorption sites are formed inside the porous channel walls. The article can be used, for example, to remove CO2 from gases.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application Serial No. 61 / 447,341, filed February 28, 2011, and U.S. Patent Application Serial No. 13 / 111,360, filed May 19, 2011, on which this document is based The contents and their entire contents are incorporated herein by reference. technical field [0003] The present disclosure generally relates to absorbent articles comprising organic-inorganic absorbent materials derived from functionalized alkoxysilanes and polyamines. These adsorption articles can be used, for example, to remove CO from gas streams 2 . Background technique [0004] Many industrial processes (such as coal gasification, biomass gasification, steam reforming of hydrocarbons, partial oxidation of natural gas, etc.) produce 2 airflow. The main problem is the aforementioned CO 2 lead to the greenhouse effect. Therefore, it is desirable to remove or capture CO from these gas mixtu...
