A research program is proposed for the investigation of the dependence of the sorptive capacity of metal/metal oxide desulfurization sorbents on their pore size distribution and their intraparticle diffusivity. Integrated reaction/adsorption systems, chromatographic and gravimetric, will be used for successive reactivity, adsorption, as well as diffusivity, measurements. Single particle models that have been developed by our research group for gas-solid reactions with solid product will be used as basis for experimental data analysis and development of a general mathematical model for fixed-bed desulfurization and sorbent regeneration.
