γ-Al_2O_3的添加对MDEA溶液脱除COS效果的影响

Effect of Addition of γ-Al_(2)O_(3) on COS Absorptivity of MDEA Solution

The addition of γ-Al2O3to industrial desulfurizer,MDEA solution,strengthened the absorptivity effect for COS.The influence of the concentration of MDEA solution and operating pressure on hydrolytic conversion of COS was investigated.The reactive system of "COS+ MDEA solution+hydrolytic catalyst" was established,which was to achieve one-step absorption for COS.The catalytic activity of prepared γ-Al2O3 was studied in this system.

The addition of y-Al2O3 to industrial desulfurizer, MDEA solution, strengthened the absorptivity effect for COS. The influence of the concentration of MDEA solution and operating pressure on hydrolytic conversion of COS was investigated. The reactive system of ＂COS ＋ MDEA solution ＋ hydrolytic catalyst＂ was established, which was to achieve one-step absorption for COS. The catalytic activity of prepared γ-Al2O3 was studied in this system.
