A Study of Gas Transport Mechanisms for CH4/CO2 Using Ceramic Membranes

Abstract

Greenhouse gas emissions (GHGs) and their effects have been a matter of global concern over the past decade. As the demand for energy grows in developing economies, there has been a challenge in harnessing and utilising sustainable forms of energy to meet these demands, and despite the effect of global warming and the problems associated with it, the use of fossil fuels is still increasing. This problem has negatively impacted the climate because greenhouse gases evolved from burning fossil fuel increase the concentration of carbon dioxide in the atmosphere and lead to global warming. This study investigates a method of channelling biogas for use as a sustainable energy source by using membrane technology. Initially, by observing the behaviour of biogas components as they travel selectively through the membrane support, the findings showed that both fluid and structural properties have significant impacts on the separation process. The next approach is to modify the membrane to obtain these optimal conditions. Furthermore, by introducing an agent that serves as an adsorptive medium for maximising contact between the pore walls and the gas molecules, this creates an adsorptive layer that preferentially draws the target gas to its surface to deliver both high permeability and selectivity of the membrane.
