Abstract
A numerical method is proposed to predict the transient of exit-gas compositions of a packed bed reactor used for gas-solid reactions. The exit-gas compositions can be predicted directly from the conversion data of a single particle varying with reaction time. Thus, the method presently proposed can be easily applied to systems involving complex reaction behavior due to structural changes of particles.
The procedure is applied to the analysis of experimental data obtained in the oxidation of reduced iron with water vapor. It is verified that the proposed numerical method successfully simulates the behavior of packed beds.
