Study on the Influence of Porous Anodic Alumina Membrane on Separation of Hydrogen and Methane

Abstract:

Hydrogen and methane have been regarded as the main energy for future. In recent years, membrane technology has developed to be an attractive technology to separate them. In this paper, porous anodic alumina membranes at different thickness were prepared for separation of hydrogen and methane. The thickness varied from about 77 to 250 μm, moreover, the SEM (Scanning Electron Microscopy) images show a good linear relationship between the thickness (y) and anodizing time (x), with the fitting being y = 22.56x - 36.082. Gas permeance and separation index for hydrogen and methane were measured at different conditions, such as thickness and temperature. With the thickness increased, the permeances of two gases were decreased quickly but separation index vice versa. In this research, the actual separation index changed from 1.9 to 3.2.
