要旨

In this work, the feasibility of an entrained flow reactor for full decarbonisation of gas streams has been proved. Three CaO-based materials (two types of lime and calcined raw meal) with different textural properties and therefore, different CO2 carrying capacities have been fed to the entrained flow reactor in a series of tests in which the Ca/CO2 molar ratio and solid residence time were the operation variables studied. Up to 11 mol CO2 m−2 s−1 has been captured from the gas phase with CaO from calcined lime with a maximum CO2 carrying capacity of 0.57 mol CO2 per mol CaO, reaching CO2 capture efficiencies over 90% for a Ca/CO2 molar ratio of 5 and solid residence times under 5 s.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
