新型油气回收吸附剂HBY-1的吸附性能研究

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200～400h-1、解吸时间为2h、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23.0g/h，高于活性炭；在油气浓度为140 000μL/L、解吸时间为2h、解吸温度为22℃时，HYB-1的吸附热比活性炭低17.1kJ/mol，而HYB-1的解吸速率为18.0g/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。

STUDY ON THE ADSORPTION PROPERTIES OF A NEW ADSORBENT HBY-1 FOR OIL VAPOR RECOVERY

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 μL/L, a space velocity of 200~400h-1, a desorption time of 2h 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 μL/L, the desorption rate of HBY-1 for oil vapor is 18.0g/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.
