浩瀚13X分子筛填充柱测定氧，氮和甲烷2米*1/8

13X molecular sieve packed column:

 

Chemical Formula: Na2O · Al2O3 · (2.8 ± 0.2) SiO2 · (6-7) H2O

Al ratio: SiO2 / Al2O3≈2.6-3.0

Applications: drying and purification of industrial gases, it may also be used in a carrier; an air separation unit feed gas purification (simultaneous removal of H2O and CO2); liquid hydrocarbons and natural petroleum gas desulfurization (removing hydrogen sulfide and mercaptans)

         Mass transfer process fluid containing adsorbable component in the adsorption column flow is very complex, usually contains axial diffusion, the shape of the mass transfer process film, macroporous diffusion and pore diffusion, which is the peak of the response of a variety of mass transfer comprehensive results of factors. Adsorption equilibrium constant and the mass transfer coefficient was measured using chromatographic techniques, it will involve the accuracy of multi-parameter estimation and the resulting parameters.

         With He as the carrier gas, computer aided measured in O_2 and N_2 at 13X zeolite packed column adsorption equilibrium constant and the mass transfer coefficient by chromatography. Made with a small amount of calculation of the Method of Moments adsorption equilibrium constant, then the total mass transfer coefficient is estimated by fitting a single time domain parameters. From the experimental results and theoretical analysis we found that the system, the axial diffusion contribution to the overall mass transfer resistance maximum, and have axial dispersion coefficient of correlation with the operating conditions.

13X stainless steel packed column applications: Separation H2, O2, N2, CH4, CO
