Equilibria data for the adsorption of hydrogen, carbon dioxide and binary mixtures of these gases are determined on activated carbon, zeolite 5A and zeolite 13X. Pure component isotherms are presented at pressure up to 30 atm and at $28\,^\circ\!C,\; 50\,^\circ\!C\; and\; 75\,^\circ\!C$.
The isotherm parameters included in various models were obtained from experimental data for the pure component systems and compared with experimental results. In pure component systems, Freundlich isotherm showed best fit with the experimental results within 5\% error.
The binary equilibria are also presented at the same temperatures as above and at pressures of 1.5 atm, 10 atm and 20 atm. The binary adsorption equilibrium data have been compared with the values predicted by various models using regression parameters obtained from the pure component isotherm.
The ideal adsorption solution(IAS) theory gave the best representation of the binary experimental data at low pressure range and LRC model gave the good representation of the binary experimental data at high pressure range.
For the purpose of modeling and design of the packed column or separation system, extended Langmuir isotherm prameters were determined directly from binary data, which represented more accurately binary experimental data.
