Title: Advanced Bio-derived Sorbents for CO2 Capture

Abstract

In 2016, 30.4% of utility electricity generation came from coal-fired power plants, which was produced through combustion of over 677 million tons of coal. The concomitant level of CO2 release necessitates transformational carbon capture technologies capable of capturing CO2 efficiently and at lower cost. After decades of research into carbon capture methods, we still do not have a favorable option. Current carbon capture technology using aqueous amine scrubbing has found a degree of usage in specific applications, but the drawbacks such as high cost, low capacity, degradation during cycling applications, and its corrosive nature have prevented widespread adoption. One potential solution is the development of high-capacity solid sorbents capable of overcoming the drawbacks faced by typical amine scrubbing. The sorbents proposed for study in this project are amine-functionalized metal organic frameworks (MOF) with specific metal centers selected based on cost and performance. The source of amine used for functionalization was chosen due to its affordable nature and the fact that it is derived from a material that is otherwise considered waste. Phase I has demonstrated successful synthesis of the modified MOF sorbent and shown that the modification is effective for increasing capacity. A novel synthesis method allowed for 270% capacitymore » increase for modified MOF compared to unmodified. Single pass CO2 selectivity was found to be 86%, and changes to the sweep gas and recycle rates could easily bring the purity to >95%. Economic analysis has determined that with scale-up, sorbent cost could remain below $10/kg which should allow for captured CO2 cost to reach $35/tonne.« less
