Abstract

LAS CERAS DE PETROLEO SON CONVERTIDAS EN LUBRICANTES DE ALTO INDICE DE VISCOSIDAD MEDIANTE UN PROCESO DE HIDROISOMERIZACION EN EL QUE LAS CERAS SON SOMETIDAS A HIDROISOMERIZACION SOBRE UN CATALIZADOR DE ISOMERIZACION DE ZEOLITA DE BAJA ACIDEZ, QUE AFECTA A LA ISOMERIZACION PREFERENCIAL DE LOS COMPUESTOS DE PARAFINA EN LA CARGA A ISOPARAFINAS DE MENOS CERA Y ALTO V. I. LA HIDROISOMERIZACION SE REALIZA A ALTA PRESION, AL MENOS A 1000 PSIG DE PRESION PARCIAL DE HIDROGENO (ENTRADA AL REACTOR) UTILIZANDO UN CATALIZADOR DE ZEOLITA, PREFERIBLEMENTE UN METAL NOBLE CONTENIENDO UN CATALIZADOR DE ZEOLITA BETA QUE CONTENGA BORO COMO COMPONENTE ARMAZON DE LA ZEOLITA, PARA DAR UN VALOR DE BAJO ALFA, TIPICAMENTE POR DEBAJO DE 10. LA HIDROISOMERIZACION SE REALIZA A 650 F EN LA PROPORCION DE 10 A 40 POR CIENTO EN PESO DE CARGA. UNA FASE DE DESCERADO FINAL A PUNTO DE FLUIDEZ PUEDE REALIZARSE CON PERDIDA RELATIVA BAJA, TIPICAMENTE DE NO MAS DE 15% EN PESO, DURANTE LA DESCERACION. EL PRODUCTO FINAL TIENE VALORES V. I. EN EXCESO DE 125 Y NORMALMENTE ENTRE 140 Y 155 Y ESTAN CARACTERIZADOS POR SU EXCEPCIONAL ESTABILIDAD.
