Researchers at Universiti Teknologi PETRONAS have made significant strides in carbon capture technology by developing mixed matrix membranes (MMMs) that enhance the separation of carbon dioxide (CO2) from methane (CH4). This innovative approach could have substantial implications for the energy sector, particularly in reducing greenhouse gas emissions associated with natural gas extraction and processing.
Led by Vinosha Viriya from the Department of Chemical Engineering, the team focused on incorporating small pore zeolite UZM-5 into a polymeric matrix made of polysulfone (PSF). The research involved synthesizing the zeolite and modifying it with a chemical agent known as 3-aminopropyltriethoxysilane (APTES). The incorporation of both modified and unmodified zeolite UZM-5 into the PSF matrix was characterized using various analytical techniques, confirming successful fabrication of the membranes.
The standout finding from this research was the impressive CO2/CH4 ideal selectivity achieved with the membranes containing 1% of the modified zeolite. This configuration demonstrated a selectivity of 33.1, representing a remarkable 212% improvement over the conventional PSF membrane. Viriya commented on the significance of these results, stating, “The enhancement in selectivity indicates that our mixed matrix membranes could be a game changer for industrial applications requiring efficient gas separation.”
The implications of this research extend beyond academic interest. With the energy sector increasingly under pressure to reduce carbon emissions, the ability to effectively separate CO2 from methane could lead to cleaner natural gas production processes. This technology could also pave the way for more efficient carbon capture and storage systems, contributing to global efforts against climate change.
As industries look for innovative solutions to meet regulatory standards and sustainability goals, the development of advanced materials like these MMMs presents a commercial opportunity. Companies involved in natural gas extraction, processing, and carbon management could benefit from adopting this technology, potentially leading to cost savings and enhanced operational efficiencies.
The findings of this research were published in the journal ‘Results in Engineering’, further solidifying its relevance in the ongoing discourse surrounding energy sustainability and environmental protection.
