Evaluation of the influence of the operational variables of catalytic reforming on the deactivation of its bimetallic catalyst at Refinery Cienfuegos S.A.
Abstract
In oil refining, there is a high consumption of chemicals and catalysts, which influences the high production costs and the environmental impact with the dumping of their residuals. It is known that at the Cienfuegos S.A Refinery there are no methodologies to systematically evaluate the behavior of the operational variables and their influence on the deactivation of the catalyst that allows establishing longer regeneration cycles. The present study aimed to evaluate the variables of the catalytic reformation process to determine their influence on the deactivation of the catalyst. In this sense, a procedure is presented that allowed the comprehensive evaluation of the process variables, where each of the steps and formulations considered are exposed and their application made it possible to identify the influences, as well as the activity of the catalyst. To facilitate operations, the IVOACRC software was designed, based on Excel conditions, with the necessary database. The most influential variables on the deactivation of the catalyst were identified, the months of catalytic activity were calculated, thus extending the useful life of the catalyst by three years.
