CO₂ Utilisation through the Production of Carbonated Salt Nanoparticles in a Rotating Packed Bed

This exciting webinar will showcase the award-winning study, which received the Best Poster Award at the 17th Greenhouse Gas Control Technologies Conference, held in Calgary, Canada, in 2024.

Synopsis

Creating new value chains by utilising captured CO₂ streams will support the growth of CCU technologies. “Hard-to-abate” industries such as cement, quicklime (CaO), and magnesite production—characterised by inherent emissions and high-temperature operations—will require CO₂ capture to align with net-zero goals.

One promising route is the utilisation of captured CO₂ for producing high-value inorganic carbonate nanoparticles. These materials can help offset the economic penalties of capture and are used in a variety of sectors, including paper, dyes, plastics, and pharmaceuticals.

However, producing these nanoparticles often involves reactor and process bottlenecks, particularly around consistent product quality. Rotating Packed Bed (RPB) reactors present a compelling solution by enabling process intensification, reducing equipment volume, improving product control, and operating under milder conditions.

In this webinar, Evie will present how her team has leveraged RPB reactors to synthesise precipitated calcium carbonate and hydromagnesite via direct aqueous carbonation. Their experimental work has demonstrated smaller particle sizes, narrower distributions, over 90% CO₂ conversion efficiency, and reduced reaction times compared to conventional methods.
