Resumen:
tDecalin, a naphthenic bicyclic compound, was reacted over a commercial FCC catalyst in its fresh, equi-librium and three dealuminated forms in order to analyze the formation of aromatic hydrocarbons in thegasoline and LCO cuts, heavy and light ends, respectively. A batch, fluidized bed CREC Riser simulatorlaboratory reactor was used at 450◦C with short contact times from 1 to 8 s. The dealuminated catalystsshowed an activity intermediate between those of the fresh and equilibrium catalysts, which can becorrelated to zeolite content and acidity. Also those properties, at least in the range of values observedin this work, seem to be the most important characteristic in controlling the selectivity of the set ofreactions. A reaction network was described, where hydrogen transfer reactions are considered to be themost important to form aromatics, a fact which is essentially unavoidable when a bicyclic naphthenicis converted on these catalysts. Aromatic belonged mainly to the gasoline boiling point range and, to alower extent, to LCO.Decalin, a naphthenic bicyclic compound, was reacted over a commercial FCC catalyst in its fresh, equi-librium and three dealuminated forms in order to analyze the formation of aromatic hydrocarbons in thegasoline and LCO cuts, heavy and light ends, respectively.
