Événement

Worldwide energy demand is projected to grow strongly in the coming decades, with most of the growth in developing countries.  Even with unprecedented growth rates in the development of renewable energy technologies such as solar, wind and bioenergy, the world will continue to rely on fossil fuels as the predominant energy source for at least the next several decades.  Simultaneously, due to decades of inaction, most current climate models suggest that limiting warming to <2>
In this lecture, I will describe the design and synthesis, characterization and application of new supported amine materials that we have developed as cornerstones of new technologies for the removal of CO2 from dilute (flue gas) and ultra-dilute (air) gas streams.3 These chemisorbents efficiently remove CO2 from simulated flue gas streams, and the CO2 capacities are actually enhanced by the presence of water, unlike in the case of physisorbents such as zeolites.  We will describe the development of these materials, how they integrate into scalable DAC technologies, as well as their key physicochemical structure-property relationships.  DAC technologies offer an interesting case study for the parallel design of materials, unit operations, and processes in chemical engineering.
