Is Cao conversion a viable option for CSP plants?

CaO conversion plays a fundamental role in the CaL process efficiency . According to Prieto et al. , the CaL system could be a viable option to be integrated in CSP plants though the authors warn that CaO deactivation can be a drawback.

How do you determine the energy storage/release capacity of Cao-based pellets?

The energy storage/release capacity of the CaO-based pellets are assessed by the CaO carbonation conversion ( X e f f, n, %), the derivative of conversion rate of carbonation ( V n, %/min) and the energy storage density ( E g, n, kJ/kg).

Which raw materials are used to make Cao based pellets?

Raw materials Calcium hydroxide (>95 wt%), a typical precursor for fabricating CaO-based pellets, was purchased from Sinopharm Chemical Reagent Co.Ltd. Microcrystalline cellulose (>99 wt%) purchased from Sinopharm Chemicals Co. Ltd. was selected as the pore-forming template.

Does granulation affect cyclic thermal energy storage/release of Cao-based pellets?

In this work, extrusion-spheronization method was adopted to produce CaO-based pellets for cyclic thermal energy storage/release. To mitigate the adverse effect of granulation on the microstructure of CaO-based pellets, the pore-forming template (i.e., microcrystalline cellulose) was added to restore their porous structures.

Are synthetic Cao-based pellets suitable for calcination?

The heat energy storage/release property of these synthetic CaO-based pellets were comparatively investigated under mild (pure N 2, 750 °C) and harsh (pure CO 2, 950 °C) calcination conditions, respectively. Moreover, the compression strength of the synthetic CaO-based pellets was tested aiming to more accurately evaluate their practicability. 2.

Does particle size affect the multicycle conversion of Cao?

The effect of particle size on the multicycle conversion of CaO is explainable from the relative thickness of the CaCO 3 layer built upon the CaO surface as compared to the size of the pores in the CaO skeleton formed after calcination and the carbonation kinetics in the fast reaction-controlled (FR) stage .
