Chemical-looping combustion (CLC) is an attractive technology to decrease greenhouse gas emissions affecting global warming, because it is a combustion process with inherent CO 2 separation and therefore without needing extra equipment for CO 2 separation and low penalty in energy demand. The CLC concept is based on the split of a conventional combustion of gas fuel into separate reduction...
The performance of zinc ferrites as desulfurization sorbents at high temperature was evaluated. Sorbents were prepared by calcination, at 650 and 1100°C, of mixtures of bulk oxides in three different stoichiometries. To calculate the global reaction rate of sulfidation in a thermogravimetric experiment, a grain model with variable properties was developed. The predicted and experimental results...
