MATHEMATICAL MODELING OF CATALYST DEACTIVATION IN THE PROCESS OF SULFATE ZIRCONIA MODIFIED WITH PLATINUM ALKYLATION

In order to predict the inactivation of these catalysts,Has been much research on the mechanisms of inactivation and different mathematical models havebeen proposed, each with certain assumptions, The results obtained are different. In this theories, SZ solid acid catalyst inactivation is modified withplatinum being covered mechanism of active sites by coke and reduction reactions, mathematical modeling has been done. Modeling the grain surface of catalysthas formulated and solution of mathematical equations obtained by MATLAB software in short time indicates that the catalyst Lost its activity andthe percent conversion to a significant drop in 10 minutes. The present study comparing the results with existing experimental results and theoretical prediction for this model is based on reliability
