(11c) High Swing Capacity MIL-101(Cr) Fiber Sorbents for Sub-Ambient CO2 Capture Via RCPSA
AIChE Annual Meeting
Sunday, October 28, 2018 - 4:08pm to 4:27pm
In this talk, after a brief review of the sub-ambient RCPSA process flow sheet, we will discuss methods of incorporating MIL-101(Cr) into fiber sorbent contactors via direct spinning. Sub-ambient CO2 isotherms show MIL-101(Cr) may be capable of swing capacities as large as 10 mmol/g, making it an ideal material for sub-ambient RCPSA. Incorporating this material into a fiber sorbent contactors make possible order of magnitude lower pressure drops as well as enabling thermal management, which increases sorbent utilization. Phase change material incorporation into the fiber sorbent during spinning, and its effectiveness as thermal modulation will be presented. The talk will focus on the application of these fibers to capturing CO2 from simulated flue gas, and will include analysis of breakthrough curves and preliminary cyclic results. These fiber sorbents containing high operating capacity sorbent materials help to support the case for applicability of the novel process design.
