  • adsorption of methane nitrogen carbon dioxide and their mixtures on wet tiffany coal
    Fuel, 2005
    Co-Authors: J E Fitzgerald, Khaled A.m. Gasem, Robert L. Robinson, Mahmud Sudibandriyo, S Reeves
    Abstract:

    Gas adsorption was measured for methane, nitrogen, CO2 and their binary and ternary mixtures on a wet Tiffany coal sample. The measurements were conducted at 327.6 K (130.0 F) at pressures to 13.8 MPa (2000 psia). The expected uncertainties in the amounts adsorbed vary with pressure and composition. In general, average uncertainties are about 5% (0.01–0.08 mmol/g) for the total adsorption; however, the expected percentage uncertainties in the amount of Individual-Component adsorption are significantly higher for the lesseradsorbed gas at lower molar feed concentrations (e.g. nitrogen in the 20/80 nitrogen/CO2 system). The Langmuir/loading ratio correlation (LRC) and the Zhou–Gasem–Robinson (ZGR) two-dimensional equation of state (EOS) are capable of representing the total adsorption for the pure, binary and ternary systems within their expected experimental uncertainties. However, the quality of fit for the Individual-Component adsorption varies significantly, ranging from 3% (0.01 mmol/g) for the moreadsorbed methane or CO2 to 32% (0.01 mmol/g) for the lesser-adsorbed nitrogen. Further, the LRC and ZGR EOS predict binary adsorption isotherms, based solely on pure-fluid adsorption parameters, within twice their experimental uncertainties. q 2005 Elsevier Ltd.

  • adsorption of methane nitrogen carbon dioxide and their binary mixtures on dry activated carbon at 318 2 k and pressures up to 13 6 mpa
    Langmuir, 2003
    Co-Authors: Mahmud Sudibandriyo, J E Fitzgerald, Robert L. Robinson, Zhejun Pan, Khaled A.m. Gasem
    Abstract:

    A detailed experimental study has been made of the adsorption of pure methane, nitrogen, carbon dioxide, and their binary mixtures on dry activated carbon (Filtrasorb 400, 12 × 40 mesh, Calgon Carbon) at 318.2 K and pressures up to 13.6 MPa. The mixture measurements were made at nominal feed-gas compositions of 20, 40, 60, and 80 mol %. The mixture data clearly elucidate the competitive nature of the Individual-Component adsorption from the mixtures. Measurements were made using a volumetric technique, coupled with gas chromatographic analysis of the equilibrium gas-phase compositions. Error propagation analysis reveals the expected average experimental uncertainties in the amount adsorbed of 2% for pure methane and nitrogen and 6% for CO2. For the mixture measurements, the uncertainties are estimated to be about 3% for the total adsorption, while the Individual-Component uncertainties vary from 0.02 to 0.2 mmol/g activated carbon, depending on the mixture composition. The data were correlated using the t...
