Calcium Looping Process an overview ScienceDirect

Calcium looping, which is a cyclic calcium oxide (CaO)-calcium carbonate (CaCO 3) process, is an option being developed for large-scale CO 2 control. It can be utilized both for precombustion carbon capture and postcombustion carbon capture, using the reversible carbonation-calcination process of as its basis.

Sintering mechanism of calcium oxide/calcium carbonate

The bond breakage and formation make the lattice structure of CaO disordered because of the reaction. The decarbonation reaction results in the density of carbon atoms lower in the surface, making the movements of internal carbon atoms and then increases diffusivities of calcium atoms. 3.4. Energy changes during sintering process

A novel method to make regenerable core-shell calcium

2006-4-1  The novelty of this sorbent is that only calcium carbonate and clay are used for its preparation with water as a binder. A two-step granulation procedure is used to get the core and then another step to coat the shell layer with the clay powder. A repeated wet-and-dry procedure probably makes the core porous yet strong enough to serve as a sorbent.
