Testing membranes for separation of CO2 from small molecules in landfill gas.

The present work is focusing on the utilization of previously fabricated membrane (synthesized in 3 days as reported in our previous work) to study the effect of hydrocarbons and its durability at the previously optimized conditions. Subsequently, gas permeation study was conducted on ceramic membranes in CO2 separation from small gas molecules present in biogas and it was found that the permeance of CO2, N2, and CH4 decreased in the order of 15 nm > 200 nm > 6,000 nm, according to the decrease in porosity of the membranes
