Abstract
|
Researchers
examined the rate and extent of a synthetic sorbent containing 83 wt% CaO, 14
wt% MgO and 3 wt% Ca12Al14O33 to react with CO2 at ∼750 °C in the presence of 5 or 10 vol%
steam. Similar to the natural sorbents and their derivatives, the rate and
extent of carbonation by the synthetic sorbent was observed to increase
substantially with the partial pressure of steam. The improvement appears to
be due to the ability of steam to promote the growth of product islands of
CaCO3 in the direction normal to the surface, as well as affecting the
porosity of the calcined material.
