- Abstract
Anthropogenic CO emission is identified as the major cause of climate change. The use of fossil fuels has to be accommodated, possibly with a CO capture process. Sequestration of captured CO at high pressure is proposed as a feasible option for future mitigation of climate change, though using fossil fuels. However, this needs significant energy input and carries the potential threat of a possible future catastrophe. Capture of CO with possible recycling is a long-term sustainable option. In this paper, a process involving a chain of reactions using solid sodium to capture both CO and SO from a flue gas is described. A significantly detailed description of both chemical reactions and physical processes is discussed. Recycling of captured CO and SO in the form of solid graphite and elemental sulphur (as the by-products) is the special feature of this process. However, critical selection of intermediate process liquids and equipment in this process needs further study for real-life implementation of this scheme.
