Mankind is dependent on energy from gas, oil, coal, atomic energy, and various other sources. In all fossil fuel combustion processes, carbon dioxide (CO ) is produced (ca. 25 Gt/year). In the past few decades, we have observed a constant increase in CO content in the air (currently ca. 400 ppm [0.04%]). This book discusses the technology related to carbon (i.e., CO ) capture and sequestration (CCS) from fossil fuel energy plants, which is considered an important means of CO control. It also covers the adsorption/absorption processes of CO on solids and similar procedures to help address growing climate change concerns.
