Abstract
A cell model has been proposed to predict the enhancement of gas absorption rates into slurries containing catalyst particles which are smaller than liquid diffusion flim thickness. The model accounts for interparticle and particle—film interactions. The finite-element technique has been used to solve the model equations. Simulations have been carried out to study the effect of catalyst loading, particle diameter, and homogeneous reaction rate constant on enhancements of the rate of gas absorption. The experimental data available in the literature have been used to verify the model. The agreement has been found to be fair, keeping in view the limitations of the experimental data. An analytical model has also been proposed to predict the upper limit of the enhancement factor.
