脱气处理 (A) Al2O3-HP and NiCoCu/Al2O3-HP, (B) Al2O3-SHP and NiCoCu/Al2O3-SHP, (C) Al2O3-CS and NiCoCu/Al2O3-CS,使用BET全自动比表面积分析仪,77K液氮条件下,对样品进行氮气吸脱附测试,得到等温吸脱附曲线,用来测定样品微孔和介孔等小孔、比表面积、 孔径分布
Degassed treatment (A) Al2O3-HP and NiCoCu/Al2O3-HP, (B) Al2O3-SHP and NiCoCu/Al2O3-SHP, (C) Al2O3-CS and NiCoCu/Al2O3-CS, Using BET automatic specific surface area analyzer, nitrogen adsorption and desorption test was performed on the sample under 77K liquid nitrogen condition, and the isothermal adsorption and desorption curve was obtained, which was used to determine the distribution of small holes, specific surface area and pore size of the sample.
