Borate-Containing Membranes for Gas Separation
Highly efficient membranes that can facilitate effective carbon dioxide capture that can be used to purify industrial gases such as natural gas, syngas, and hydrogen
Membranes are a cost-effective and energy-efficient solution for the separation of carbon dioxide from methane and industrial flue gas. In addition, membranes are utilized to purify hydrogen and syngas. Increased global utilization of natural gas has necessitated efficient natural gas purification technologies. Investment in hydrogen purification technologies is growing due to a significant demand for hydrogen in the petroleum refining and renewable energy industries. Concerns about greenhouse gas emissions and their impacts on global climate change have generated a demand for membranes capable of efficient CO2 purification and capture from fossil fuel combustion activities.
Researchers at The Ohio State University, led by Dr. Winston Ho, developed borate-containing membranes for selective separation and purification of industrial gases. This high-temperature facilitated transport membrane uses air to sweep gas in the gas separation processes.
