Calcium acetate as a sorbent precursor for the removal of carbon dioxide from gas streams at high temperature
TL;DR: The feasibility of a process for the high-temperature, high-pressure separation of CO2 from coal-derived gas streams based upon the noncatalytic gas-solid reaction CaO(s)+CO2(g) ⇆ CaCO3(S) is being investigated as mentioned in this paper.

A structural model for gas-solid reactions with a moving boundary-II: The effect of grain size, porosity and temperature on the reaction of porous pellets
J. Szekely,James Evans +1 more
TL;DR: In this article, a structural model is presented for the non-catalytic reaction between a porous solid and a gas stream, which incoporates parameters such as solid grain size, porosity, effective pore diffusion coefficient and allows the quantitative assessment of the role played by these in determining the overall reaction rate.

The variable property grain model applied to the zinc oxide-hydrogen sulfide reaction
P.V. Ranade,Douglas P. Harrison +1 more
TL;DR: The variable property grain model, including the effect of grain diffusion resistance, has been applied to experimental results from the reaction of hydrogen sulfide with zinc oxide as discussed by the authors, where grain radius is assumed to vary under the combined effects of sintering and extent of reaction property variations are correlated by the specific surface area.
