Liquid-phase adsorption of binary mixtures of alkanes

The isotherms of excess adsorption of mixtures of n-octane and n-hexadecane and isooctane and n-hexadecane on different adsorbents-activated carbons TA 120 and TA 95, silica gel, and zeolite 5A-were determined. The expediency of using zeolite 5A for separation of n-alkanes was established. The excess adsorption of the components was quantitatively described with T. Kind’s equation. The constants in this equation were determined with the experimental data obtained on zeolite 5A. The adequacy of the equation was demonstrated by comparing the calculated and experimental data and with Fisher’s criterion. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 4, pp. 45–46, July–August, 2006.     

Optimization of Liquid-phase Processes in a Stationary Bed of Adsorbent

Protecting the environment from pollution by harmful industrial emissions is a global problem whose solution involves creating environmentally clean plants. Not only fundamental changes in the technology but also the development of new and reconstruction of existing units [1] based on modern methods of systems analysis are required for creating such plants.
