Abstract

Mathematical models have been developed for the design of bubble column slurry reactors wherein the particles with nonuniform distribution of solid reactant take part in the reaction and follow the shrinking core model. The cases of external mass transfer control, ash layer diffusion control and chemical reaction control have been analyzed using solid distribution functions presented by Dudukovic (1984). It was found that the nonuniformity of solid reactant can strongly affect the reactor performance. Correction factors for modifying the performance charts of Joshi el al. (1981) who considered only uniform solid reactant distribution are presented for design and scale-up purposes.
