使用 BET全自动比表面积分析仪, 77k液氮条件下,对样品 Al2O3-HP,Al2O3-SHP,Al2O3-CS,Ni/Al2O3-HP,NiCo/Al2O3-HP,NiCoCu/Al2O3-HP,NiCoCu/Al2O3-SHP,NiCoCu/Al2O3-CS进行氮气吸脱附测试,待仪器分析完毕得到等温吸脱附曲线,再用BET、 BJH、 HK等模型数据处理。
Using BET automatic specific surface area analyzer, 77 k liquid nitrogen condition, Pair sample Al2O3 - HP, Al2O3 - SHP, Al2O3 - CS, Ni/Al2O3 - HP, NiCo/Al2O3 - HP, NiCoCu/Al2O3 - HP, NiCoCu/Al2O3 - S HP,NiCoCu/Al2O3-CS were tested for nitrogen adsorption and desorption. After instrument analysis, isothermal adsorption and desorption curves were obtained, and then BET, BJH, HK and other model data were used for processing .
