제올라이트 흡착도 isotherm 곡선을 실험결과로 그리는 실험결과 보고서입니다
목차
1. Result
2. Discussions
1) Draw the adsorption-desorption isotherms for n-hexane and 2-methylpentane.
2) Comparing the n-hexane and 2-methylpentane isotherms. Correlate the pore structure of 5A (CaA) zeolite and the isotherms.
3) Although the kinetic diameter of 2-methylpentane is larger than the pore aperture size of 5A, 5A showed some adsorption amount even for 2-methylpentane. Explain it.
3. Analysis
1) Error Analysis
2) Use of He gas for determining the cell volume
3) Difference between adsorption/desorption isotherm – Hysteresis loops
4) Adsorption dependence on pressure
4. Reference
본문내용
Both isotherms shows increase as the equilibrium pressure increase, but the adsorption of n-hexane is much higher than the other. The pore aperture size of CaA zeolite is 4.5A. n-hexane and 2-methypentane have the same molar mass, so van der Waals force between zeolite and each molecule specie are similar. However, kinetic diameter of n-Hexane is 4.3A, which is smaller than CaA zeolite pore size. So n-hexane can get into the zeolite pore easily, and it shows high adsorbance.
