Resumen

BOCANEGRA, S; SCELZA, O  y  DE MIGUEL, S. Modification of selectivity and carbon deposition during the initial stages of the n-butane dehydrogenation over mono and bimetallic catalysts. Lat. Am. appl. res. [online]. 2013, vol.43, n.2, pp.131-135. ISSN 0327-0793.

The initial carbon deposition and the generation of dehydrogenating selectivity during the initial steps of the reaction are investigated for Pt and PtSn catalysts supported on pure and Na-doped alumina by using a pulse technique (injection of n-butane pulses). Results demonstrate that Pt support-ed on pure alumina is not a proper dehydrogenation catalyst. It shows a high hydrogenolytic and cracking behavior and an important carbon formation that deactivates the catalyst. However the combined presence of tin and sodium inhibits not only the car-bon deposition reactions but also the C-C breaking reactions, increasing in an important way the dehy-drogenating selectivity to the different butenes to a value about 80%
