摘要
对新型油气回收吸附剂HBY-1的吸附、解吸性能进行了研究。试验结果表明,室温下,在甲苯浓度为10 000μL/L、空速为200～400 h^(-1)、解吸时间为2 h、解吸温度为22℃时,HBY-1对甲苯的平衡吸附容量为28.0%,解吸速率为23.0 g/h,高于活性炭;在油气浓度为140 000μL/L、解吸时间为2 h、解吸温度为22 ℃时,HYB-1的吸附热比活性炭低17.1 kJ/mol,而HYB-1的解吸速率为18.0 g/h,是活性炭解吸速率的1.5倍,说明HYB-1的安全性和回收性能均优于活性炭。
The adsorption and desorption properties of a new adsorbent HBY-1 for recovering oil vapor were studied. Results show that under the conditions of room temperature, a toluene concentration of 10 000/LL/L,a space velocity of 200--400 h-1 ,a desorption time of 2 h and a desorption temperature of 22℃ ,the adsorption capacity of HBY-1 for toluene is 28.0% and desorption rate reaches 23.0 g/h which is higher than that of activated carbon（11. 6 g/h）; under the conditions of oil vapor concentration of 140 000 I^L/L, the desorption rate of HBY-1 for oil vapor is 18.0 g/h which is higher than that of activated carbon（12. 0%）,and the adsorption heat of the new adsorbent is 17. 1 kJ/mol lower than that of activated carbon. It can be seen that adsorbent HBY-1 is more effective in recovering oil vapor and safety in use.
