VOLTAGE-SWING METHOD FOR CARBON CAPTURE USING POROUS CARBONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17808572 titled 'VOLTAGE-SWING METHOD FOR CARBON CAPTURE USING POROUS CARBONS

Simplified Explanation

The abstract describes a method and system for capturing carbon dioxide using a voltage-swing approach. Here is a simplified explanation of the abstract:

  • The invention proposes a method and system for capturing carbon dioxide from a gas mixture.
  • The process involves using a sorbent material that can selectively adsorb carbon dioxide through physisorption.
  • To increase the sorbent's selectivity and adsorption capacity, a positive electrical charge is applied to the sorbent.
  • This positive charge enhances the sorbent's ability to capture carbon dioxide from the gas mixture.
  • Once the carbon dioxide is captured, it can be liberated from the sorbent by removing the positive electrical charge and applying a desorption method.
  • The desorption method helps release the carbon dioxide from the sorbent, allowing it to be collected and stored.

Potential applications of this technology:

  • Carbon capture and storage systems in power plants and industrial facilities.
  • Reduction of greenhouse gas emissions from fossil fuel combustion processes.
  • Carbon dioxide capture in natural gas processing and biogas purification.
  • Carbon capture in the production of hydrogen and other industrial processes.

Problems solved by this technology:

  • The method provides an efficient and selective approach for capturing carbon dioxide from gas mixtures.
  • It addresses the need for effective carbon capture technologies to mitigate climate change and reduce greenhouse gas emissions.
  • The voltage-swing approach improves the sorbent's selectivity and adsorption capacity, enhancing the overall carbon capture process.

Benefits of this technology:

  • Increased efficiency in capturing carbon dioxide from gas mixtures.
  • Selective adsorption of carbon dioxide, reducing the capture of other gases.
  • Potential for large-scale implementation in various industries.
  • Contribution to mitigating climate change by reducing greenhouse gas emissions.


Original Abstract Submitted

A method and system for carbon capture through a voltage-swing is provided. The present invention may include capturing carbon dioxide from a gas mixture through physisorption by applying a positive electrical charge to a sorbent to increase the sorbent's selectivity and adsorption and liberating the carbon dioxide from the sorbent by removing the positive electrical charge from the sorbent and applying a desorption method to the sorbent.
