Title: David G. Madden: Gas-Separation Innovation

Introduction

David G. Madden is an inventor associated with the University of Limerick in Limerick, Ireland. His patent work addresses methods for separating gases from complex mixtures using multiple sorbent materials.

Latest Patents

Madden is associated with 1 patent, concerning the purification of gaseous mixtures. The disclosed method contacts a mixture containing a target gas and at least two other gases with sorbent media made from two or more sorbent materials. One material preferentially adsorbs the first gas over the target gas, while another preferentially adsorbs the second gas over the target gas. This approach can help obtain gases such as ethylene, methane, or propylene. The patent also describes sorbent media and apparatus for carrying out the separation.

Career Highlights

Madden’s listed innovation focuses on selective adsorption as a way to purify multicomponent gas mixtures. The work’s potential applications include separating valuable gases from mixtures containing several components.

Collaborations

Madden’s listed coworkers include Amrit Kumar and Michael Zaworotko. His work is associated with the University of Limerick.

Conclusion

David G. Madden’s patent work explores how combinations of selective sorbents can improve the separation of target gases from complex mixtures.
