Abstract (type = abstract)
Supported catalysts are widely used in many industries. Manufacturing these catalysts is extremely complex and these processes are influenced by many interdependent parameters. Although their performance and activity are the most critical properties, their structures and design are also critical to their effectiveness. Research work showed how the adsorption of metal on the catalyst support and film breakage could significantly influence metal distributions at lower concentrations. A nickel nitrate hexahydrate-alumina system was studied. It was observed that at higher concentrations, the adsorption parameters were no longer the controlling factor, and solution properties began to take over the metal distribution characteristics. Solution properties like density, viscosity, surface tension and volume ratio of metal begin to take over the metal distribution at these high concentrations. At very high concentrations (about 3.0 M), a uniform metal distribution profile was observed due to the high concentration and low melting point of the metal salt, leading to a molten liquid phase during drying. This model which was based on nickel nitrate hexahydrate, exhibited a good agreement with experimental results. To apply this model to other metal-support systems, a lot of experiments would have to be repeated to determine the metal solution properties as they are unique to different metal-support combinations. In this thesis, we designed and created a simplified model based on the high-concentration nickel nitrate hexahydrate model. This model can be applied to other metals on an Alumina support and can simulate their metal distributions after the drying process. Designing this model involved a detailed analysis of each of the solution based parameters and adsorption parameters considered for nickel nitrate. A reduced parameter model involving fewer parameters was developed and tested using a new metal precursor - cobalt nitrate hexahydrate. Experiments were then performed for cobalt nitrate hexahydrate on alumina supports and their parameters were incorporated into the model. Post drying metal distributions for different concentrations of the metal solutions were generated using this model.
