Experimental analysis of CO2 frost front behaviour in moving packed beds for cryogenic CO2 capture

In this work, the feasibility of a novel method cryogenic carbon capture based on dioxide frost deposition onto cold moving bed is explored. As gas mixture including CO2 flows through sufficiently packed bed, deposited material as frost. warmed by stream front advances bed. Experimental measurements rate advance within static are used to set up achieve continuous removal. Precooled and dry binary mixtures nitrogen determine velocity in column. The measured fixed experiments with varying concentrations flow rates range 0.4–1 mm/s. experimental results were design system that would match velocities so be possible. Experiments conducted investigate behaviour temperature profiles column under conditions. These show accumulation does not occur successfully demonstrates capture.
