Microencapsulation of Advanced and Novel CO2 Sorbents

We present an application of microencapsulation for advanced solvents and materials as carbon dioxide sorbent systems. Current research into advanced technical solvent systems has focused on the key elements of kinetics of absorption, material carrying capacity of carbon dioxide, loading and unloading times, and solvent viscosities, among other properties. While some of these properties may be optimized against current carbon capture schemes, there still exist hurdles towards their implementation.
To overcome these shortcomings, we present a motif of encapsulation of these advanced solvents, such as CO2BOLS and NOHMS, in a CO2 permeable shell material, in the form of a microcapsule. Issues of slow absorption, interaction with infrastructure, and high viscosities of materials can be minimized using this technique, and optimization of specific surface area and viscosity changes are engineered into the absorption system.

We present current work and progress on encapsulation of these systems are their performance against conventional absorption systems and techniques.
