Contribution à l’étude des catalyseurs bifonctionnels appliqués au reformage catalytique et optimisation de leurs conditions de mise en œuvre : corrélation entre distributions des sites actifs et performances attendues dans un réacteur à lit fixe

Abstract

We have analyzed, on the one hand and from an industrial aspect, the performances of a bifunctional bimetallic catalyst 2 3 Pt Re/ Al O of the catalytic reforming plant of naphtha samples obtained from Algerian crude oil in the refinery of Skikda. On the other hand , and in order to enhance the performances of the reactors, which are considered to be black boxes, in the refinery of Skikda, we suggest a mathematical heterogeneous model which shows the impact of the non uniform distribution of the active sites of Pt, Re and acid on the reformate production. Most mathematical models in the literature are homogeneous while the naphtha catalytic reforming process is known to be intrinsically heterogeneous
