Research on Application Analysis of Fractal Theory in Carbon Dioxide Adsorption

Abstract

In this paper, the porous media space of adsorption tower was treated from a new perspective according to the brief introduction of fractal theory. In order to identify the method on describing specific diffusion characteristics of fractal porous media space, the diffusion mechanism in adsorption tower was studied by fractal characteristic variables. It was determined whether heat transfer and mass transfer of porous media adsorbent could be coupled well under the certain fractal dimension. As a result, the preferably matched heat transfer rate and adsorption-desorption rate under the selection of adsorbent with appropriate fractal dimension and suitable adsorption bed structure not only improves heat transfer rate but also ensures mass transfer rate, which provides a theoretical basis for the practical application.
