The study on the adsorption capacity of adsorbent XF-4 adsorption to CO_2, CH_4, NH_3 and H_2S in the cowshed

Shao Wei;Zhang Xiaofei;Yu Xiong;  
This experiment tested the adsorption capacity to CO_2, CH_4, NH_3 and H_2S of materials adsor-bent XF-4 in the cowshed. Take suspension adsorbent as the experimental group, and the controlgroup had no adsorbent. The different values between the two groups were the adsorption concentrationof XF-4. Use the ideal gas state equation to deduce formula according to the actual measured tempera-ture, atmospheric pressure and wind speed. Put ppm being converted to mg/m3, stop the test whenthere was no obvious difference between the experimental group and control group. The experimentaldata showed that 1 kg of adsorbent XF-4 can adsorb CO_2 73.21 g, CH_4 10.06 g, NH_3 1.52 g and H2S2.05 g in spring, adsorb CO_2 70.47 g, CH_4 9.23 g, NH_3 1.67 g and H_2S 2.13 g in summer, adsorb CO_278.75 g, CH_4 10.97 g, NH_3 2.05 g and H_2S 1.86 g in autumn, adsorb CO_2 85.95 g, CH_4 12.36 g, NH_32.87 g and H_2S 1.88 g in winter. The adsorption to CO_2, CH_4 and NH_3 had significant negative relation-ship with the temperature(P0.05), and they had significant positive relationship with the humidity(P0.01 or P0.05), it also had positive relationship with the gas initial content(P0.05). The adsorption toH_2S was negative related to the humidity(P0.05) and positive related to the temperature(P0.01).
