Reliable Laboratory Reactor Data Analysis: Evaluation of Commercial FCC Catalysts in a Batch Fluidized Bed Reactor

Daniel Del Río; Francisco J. Passamonti; Ulises Sedran

Statistical techniques for the treatment and analysis of experimental data from laboratory reactors were considered, as applied to a CREC Riser Simulator reactor for the example of fluid catalytic cracking catalyst evaluation. Deviations in mass balances were reconciliated considering the variance in each product mass. After reconciliations, simple optimum performance envelope curves were used to fit the data due to their simplicity and proper representation of the yield curves. In the data fitting step, errors in both dependent and independent variables were considered by using information obtained in the reconciliation procedure. The impact of different levels of confidence bands in the models on the discrimination of experimental results was discussed. Significant improvements in catalyst evaluation could be achieved either in the CREC Riser Simulator or other types of laboratory reactors with the help of the statistical procedures described here without increasing substantially the number of experiments.

Vapor Pressure of Saturated Aqueous Solutions of Potassium Sulfate from 310K to 345K

Francisco J. Passamonti; Abel Cesar Chialvo

The experimental evaluationof the vapor pressure of saturated aqueous solutionsof potassiumsulfate wascarried out in the range of temperatures 310K ≤ T ≤ 345K. The experimental data were used to determine the corresponding values of the water activity in such solutions.The analytical expressions as a function of temperature of both, vapor pressure and water activity, were obtained from the correlation of the experimental results. The vapor pressure expression was also extrapolated to a different temperature range in order to make a comparison with the results obtained by other authors.
