Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

For the postcombustion CO 2 capture by the Na 2 CO 3 dry sorbents, system integration of CO 2 capture into an existing coalfired power plant is of great significance, as the huge energy consumption of CO 2 capture results in great efficiency penalty. By system integration optimization, nearly 80% of the low temperature energy released from the CO 2 capture could be recovered to gain more ...
