Se estudi la reaccin de isomerizacin de npentano sobre catalizadores Pt/MOR (1% p/p), con relaciones Si/Al desde 5 hasta 35. El platino fue incorporado a la zeolita mediante intercambio inico en estado slido. Los slidos fueron caracterizados por energa dispersiva de rayos X (EDX), difraccin de rayos X (XRD), termodesorcin programada de amonaco (TPDNH3) y adsorcin/desorcin de N2 a 77K. Las reacciones fueron llevadas a cabo a diferentes temperaturas, observndose un aumento en la actividad del catalizador con el aumento de temperatura, pero tambin una disminucin de la selectividad hacia isopentano. La conversin inicial es una funcin lineal de la concentracin de sitios cidos del catalizador, y est relacionada tambin con el volumen de poro de la zeolita. La selectividad de estos catalizadores depende de la distribucin de la fuerza de los sitios cidos, siendo los sitios cidos dbiles los que favorecen la isomerizacin.
