Abstract
UN PROCESO PARA LA PREPARACION DE UN ACEITE BASICO LUBRICANTE QUE CONSISTE EN PONER EN CONTACTO UNA CARGA DE HIDROCARBURO CON UN CATALIZADOR EN PRESENCIA DE HIDROGENO, CUYO CATALIZADOR CONTIENE UN COMPONENTE DE HIDROGENACION SOPORTADO EN UN SOPORTE DE SILICE-ALUMINA AMORFO QUE TIENE UNA MACROPOROSIDAD DE ENTRE UN 5% EN VOL. Y UN 40% EN VOL. LA CARGA DE HIDROCARBURO ES PREFERENTEMENTE UNA CERA APAGADA O UNA CERA SINTETICA. EL CATALIZADOR PREFERENTE A UTILIZAR EN EL PROCESO CONSTA DE UNA COMBINACION DE UNO O MAS DE LOS METALES COBALTO, HIERRO Y NIQUEL Y UNO O MAS DE LOS METALES CROMO, MOLIBDENO Y TUNGSTENO O UN SOPORTE DE SILICE-ALUMINA AMORFO QUE TIENE UNA MACROPOROSIDAD DE ENTRE UN 5% EN VOL. Y UN 50% EN VOL. ESTE CATALIZADOR ES ESPECIALMENTE PREFERENTE CUANDO LAS CARGAS DE HIDROCARBUROS SE TRATAN DE MODO QUE CONTENGAN CANTIDADES SIGNIFICATIVAS DE COMPUESTOS QUE CONTENGAN NITROGENO Y AZUFRE.
