Abstract

PROCEDIMIENTO PARA LA OBTENER AZUCARES POR HIDROLISIS CONTINUA DE HERMECELUSOSAS QUE CONTIENEN PENTOSANAS D%E CELULOSA Y COMPUESTOS CORRESPONDIENTES EXISTENTES EN BIOSUSTANCIA VEGETAL. CONSISTENTE EN UNA PRIMERA ETAPA DE HIDROLISIS DE LA BIOSUSTANCIA PREVIAMENTE TRITURADA MEDIANTE ACIDO DILUIDO A TEMPERATURA ENTRE 135C Y 190C Y PRESION CORRESPONDIETE, FORMANDOSE PENTOSAS Y PARCIALMENTE HEXOSAS. EN UNA SEGUNDA ETAPA, A TEMPERATURAS ENTRE 210C Y 250C, SE HIDROLIZA CELULOSA EXISTENTE EN LA BIOSUSTANCIA PARA FORMAR EXOSAS. EN AMBAS ETAPAS SE EFECTUAN REDUCIONES SUBITAS DE LA PRESION, SEPARANDOSE EL HIDROLIZADO DE LA BIOSUSTANCIA, CON LO QUE ELHIDROLIZADO NEUTRALIZADO PARA LA OBTENCION DE AZUCARES. EL PROCEDIMIENTO SE VERIFICA EN UNA INSTALACION EN LA QUE LA BIOSUSTANCIA SE INTRODUCE POR MEDIO DE UN TORNILLO SIN FIN DE CARGA EN EL RECINTO DE REACCION CONSTITUIDO POR UN DIGESTOR TUBULAR HORIZONTAL CONTINUO EN EL QUE SE VERIFICA LA HIDROLISIS EN FASE DE VAPOR.
