Molten carbonate fuel cell (MCFC)/gas turbine (GT) hybrid system has attracted a great deal of research effort due to its higher electricity efficiency. However, its technology has remained at the conceptual level due to incomplete examination of the related issues, challenges and variables. To...

The present paper investigates the application of raw coal fly ash (FA) to dry-based CO2 fixation. Dry sorbents are manufactured by mixing FA, NaOH, CaO and a small amount of water and their absorption behavior, performance, regeneration and leaching efficiency are analyzed. The CO2 absorption...

The leaching and carbonation performances of indirect mineral carbonation are investigated using coal fly ash (FA) as the raw source and water as the solvent. The reactions were conducted at ambient temperature and pressure with a gas mixture comprised of 15 and 33mol% CO2. The overall CO2...
