Characterization and Gas Separation Performance of Two High Performance Polyimide Blend Membranes

摘要

The emission of greenhouse gases, generated by human industrial activities, is perhaps the most prominent environmental problem today. In recent years, CO2 has attracted much attention because it is the most important human induced greenhouse gas and is believed to be responsible for approximately 64% of the enhanced greenhouse effect. Carbon Capture and Sequestration (CCS) is considered as a promising way to reduce the CO2 concentration in the atmosphere. According to the IEAs 2°C scenario report, the CO2 emissions should be decreased to 14 billion tons per year in 2050, and CCS should be responsible for approximately 20% of this reduction.
