Adsorption and desorption of hydrocarbons at low concentrations
Research accomplishments during the report period include the following: (1) experimental measurements of the time-dependent transmission of hydrocarbons and their mixtures at low concentrations through activated carbon and polystyrene adsorbed beds; (2) theoretical and experimental studies of dynamics of adsorbates (including radioactive gases) in adsorbed beds; (3) formulation of the theory of adsorption of single gases and their mixtures on heterogeneous microporous solids; (4) initial studies of adsorption from solutions on heterogeneous microporous solids; and (5) study of the influence of adsorbent heterogeneity on the pressure swing adsorption process. During the report period, the chromatographic dynamic method for measuring transmission of gases and gas mixtures through adsorbent beds was improved and modified in order to cover very low adsorbate concentrations and low temperatures. The transmission measurements were utilized to study diffusion effects for gases and gas mixtures flowing through adsorber beds and to calculate equilibrium adsorption isotherms for single gases and gas mixtures. Significant progress has been achieved in the theory of gas adsorption on heterogeneous microporous solids and in the characterization of structural and energetic heterogeneities of these solids.
