Abstract

Un procedimiento para efectuar una isomerización catalítica de compuestos hidrocarbonados aromáticos mocíclicos sustituidos con metilo, de 8 a 10 átomos de carbono, contenidos en un material de alimentación que contiene también etilbenceno, que comprende poner en contacto dicho material de alimentación en fase de vapor con un catalizador que comprende una zeolita de aluminosolicato cristalina que tiene un índice de restricción en el intervalo de 1 a 12, conteniendo dicha zeolita hidrógena, precursor de hidrógeno y/o cationes metálicos del grupo VIII, a una temperatura de 316ºC a 482ºC, una presión de 0 kg/cm2 manométricos a 35 kg/cm2 monométricos, una relación molar hidrógeno/hidrocarburos de 0 a 10 y una velocidad espacial horaria en peso entre 0,1 a 200, habiéndose puesto en contacto dicho catalizador con uno o más compuestos de nitrógeno básicos o sus precursores, siendo la relación resultante de átomos de nitrógeno/átomos de aluminio en la zeolita de 0,01 a 1,0.
