Integrated CO2 Capture and Conversion to Methanol Using Zeolite Membrane Reactor

Capturing CO₂ from stationary sources, such as power plants and industrial facilities, is essential in addressing climate change. These sources are major emitters of greenhouse gasses, and without mitigation efforts, they significantly contribute to global warming. Carbon capture technologies can reduce the carbon footprint of these industries while allowing vital economic activities to continue, Additionally, captured CO₂ can be repurposed for carbon utilization, converting waste into valuable resources and supporting a transition to a low carbon and circular economy.

 

Researchers at Arizona State University have developed an innovative system that captures CO₂ emissions from coal plants and converts them into high-purity methanol using renewable hydrogen. This technology integrates a high-pressure zeolite membrane reactor for CO₂ hydrogenation with a temperature swing adsorption (TSA) unit for CO₂ capture, creating a synergistic system that enhances efficiency and sustainability.

 

This system not only provides a practical solution for mitigating CO₂ emissions but also contributes to advancements in clean technology, supporting environmental sustainability and promoting a circular economy.
