THE ROLE OF SOLIDS IN CO_2 CAPTURE: A MINI REVIEW

摘要

Solid-based CO_2 capture processes, while not having received the level of attention given to gas absorption processes, possess many potential advantages including high operating temperature and avoidance of liquid wastes. This paper discusses recent developments in both the low and high temperature capture of CO_2 from flue gases, sorption enhanced H_2 production and chemical looping combustion. The latter processes include CO_2 capture as an integral step in the overall process.
