Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA FABRICACION DE PAPEL VIEJO CON UNA SEPARACION DE TINTA TIPO LITOGRAFICA ENZIMATICA, DONDE A) SE AJUSTA BAJO UNA DOSIFICACION AL MISMO TIEMPO DE AGENTES DE OXIDACION Y REDUCCION HACIA UNA SOLUCION QUE CONTIENE UN PAPEL VIEJO, UN POTENCIAL REDOX DE 200 A 500 MV. B) COMIENZA UNA REACCION QUE TIENE POCO LIGNIN MEDIANTE ADITAMENTOS DE ENZIMAS LIGNOLITICOS. C) PROSIGUE LA REACCION BAJO ADITAMENTOS DE 60 A 80 L/HORAS AIRE POR CADA 1,51 DE VOLUMEN DE REACCION A 40 (GRADOS) C, DE 0,8 A 2,5% DE LA DENSIDAD DE SUSTANCIAS Y DE UNA VELOCIDAD DE AGITACION 1.220 A 1.600 RPM EN UNA INSTALACION DE FLOTACION COMERCIAL Y CORRIENTE PARA CERCA DE 10 MINUTOS Y D) LA REACCION CONTINUA EVITANDO LA ADMISION DE UNA VELOCIDAD DE AGITACION REDUCIDA DE 60 A 90 MINUTOS.
