Improved Eutectic Based Solvents for Capturing Carbon Dioxide (CO2)

Capturing Carbon Dioxide From Air

The goal of carbon sequestration is to take CO2 that would otherwise accumulate in the atmosphere and put it in safe and permanent storage. Most proposed methods would capture CO2 from concentrated sources like power plants. Indeed, on-site capture is the most sensible approach for large sources and initially offers the most cost-effective avenue to sequestration. For distributed, mobile source...

Imidazole tailored deep eutectic solvents for CO2 capture enhanced by hydrogen bonds.

Deep eutectic solvents (DESs) have emerged as promising alternative candidates for CO2 capture in recent years. In this work, several novel DESs were firstly prepared to enhance CO2 absorption. Structural and physical properties of DESs were investigated, as well as their absorption performance of CO2. A distinct depression in the melting point up to 80 K of DESs was observed compared with that...

Ventilation Efficiency and Carbon Dioxide (CO2) Concentration

In animals metabolic processes, involve complex organic molecules being broken down to simpler molecules, such as carbon dioxide and water. Carbon dioxide waste is removed from the body through respiration. Carbon dioxide content in fresh air is approximately 400 parts per million. In this study, we investigate the relationship between ventilation efficiency and carbon dioxide (CO2) concentrati...

Capturing carbon dioxide as a polymer from natural gas

Natural gas is considered the cleanest and recently the most abundant fossil fuel source, yet when it is extracted from wells, it often contains 10-20 mol% carbon dioxide (20-40 wt%), which is generally vented to the atmosphere. Efforts are underway to contain this carbon dioxide at the well-head using inexpensive and non-corrosive methods. Here we report nucleophilic porous carbons are synthes...
