Two Patents Filed for New Solvents for CO2 Capture Process

As both the interest and the urgency to capture and transform carbon dioxide (CO₂) emissions increases, Circa has developed two new CO₂ solvents from its platform molecule, levoglucosenone (LGO).

The two new solvents named Furatech:1 and Furatech:2 are the product of 12 months of development and testing across a range of new LGO- based molecules within Circa’s R&D team.

The Furatech products have been designed to be used in several current CO₂ capture processes and discussions are underway about further optimisation with our engineering partners.

“Applying for patents is a major step, and we are sufficiently excited about the performance of these two new CO₂ solvents that getting protection in place as quickly as possible is a priority,” says Tony Duncan, Circa CEO. “Furatech testing has shown good CO₂ capture performance across multiple cycles, as well as lower energy requirements in the desorption phase compared to current industry standards.”

With the ReSolute plant commissioning planned for mid-2024, further testing and trialling of Furatech:1 and Furatech:2 will continue in parallel.
