Abstract

SE PRESENTA UN PROCESO PARA REFINAR UNA FRACCION DE SUMINISTRO CON CONTENIDO DE AZUFRE QUE HIERVE EN LA BANDA DE EBULLICION DE LA GASOLINA. LA CORRIENTE DE SUMINISTRO SE PONE EN CONTACTO CON UN CATALIZADOR DE HIDROTRATAMIENTO, QUE COMPRENDE A) UN ZEOLITO QUE TIENE UN INDICE DE COMPRESION DE 1 A 12, PREFERIBLEMENTE MCM22, B) UN METAL DEL GRUPO VI, C) UN METAL DEL GRUPO VIII, Y D) UN SOPORTE REFRACTARIO, BAJO CONDICIONES DE HIDROTRATAMIENTO SUFICIENTES PARA PRODUCIR UN PRODUCTO QUE COMPRENDA UNA FRACCION NORMALMENTE LIQUIDA QUE HIERVE SUBSTANCIALMENTE EN LA MISMA BANDA DE EBULLICION QUE LA FRACCION DE SUMINISTRO, PERO QUE TIENE UN MENOR CONTENIDO DE AZUFRE Y UN OCTANAJE SUBSTANCIALMENTE NO INFERIOR A LA FRACCION DE SUMINISTRO.
