Abstract
This paper presents the experimental results of different methods of characterization carried out on a gamma alumina ceramic membrane. A commercial gamma alumina mesoporous membrane has been used. The pore size, specific surface area and pore size distribution values were calculated with the use of a nitrogen adsorption-desorption instrument. The images from the scanning electron microscopy (SEM) showed the membranes’ morphological structure. Gas permeation tests were carried out on the membrane using a variety of single and mixed gases at a temperature range between 25–200 °C and gauge pressure range of 0.05–1 bar. Graphs of flow rate versus temperature were obtained. The results were therefore used to explain the effect of temperature on the flow rate of the various gases. At a pressure drop of 0.5 bar for example, the flow rate for N2 was relatively constant up to 150 °C before decreasing with further increase in temperature, while for O2, it continuously decreased with an increase in temperature.
