Optimization of Laccase/Mediator System (LMS) Stage Applied in Fractionation of Eucalyptus globulus
Loaiza Rodríguez, Javier Mauricio; Alfaro Martínez, Ascensión; López Baldovín, Francisco; García Domínguez, María Trinidad; García Domínguez, Juan Carlos (MDPI, 2019)
In a biorefinery framework, a laccase/mediator system treatment following autohydrolysis was carried out for eucalyptus wood prior to soda-anthraquinone pulping. The enzymatic and autohydrolysis conditions, with a view to ... -
Optimization the soda-AQ process for cellulose pulp production and energy content of black liquor from L. leucocephala K360
Feria Infante, Manuel Javier; García Domínguez, Juan Carlos; Díaz Blanco, Manuel Jesús; Garrote Velasco, Gil; López Baldovín, Francisco (Elsevier, 2012)
A commercial variety of Leucaena leucocephala K360 was used for pulp production and papermaking employing the soda-anthraquinone process. Also, the chemical and energy contents of the resultant black liquors were determined ... -
Organosolv pulping of olive tree trimmings by use of ethylene glycol/soda/water mixtures
Jiménez, Luis; Rodríguez, A.; Díaz Blanco, Manuel Jesús; López Baldovín, Francisco; Ariza Carmona, José (De Gruyter, 2004)
This paper reports on the influence of independent variables in the ethylene glycol/soda pulping of olive wood trimmings (165–1958C, 30–90 min, ethylene glycol concentration 5–15%, soda concentration 2.5–7.5% and ... -
Paulownia as a rawmaterial for the production of pulp by soda-anthraquinone cooking with and without previous autohydrolysis
García Domínguez, Juan Carlos; Zamudio, Minerva A. M.; Pérez Muñoz, Antonio; Alva Salazar, Hugo Eduardo de; López Baldovín, Francisco (Wiley, 2011)
BACKGROUND: A central composite experimental design and multiple regression were used to model the production of pulp and paper sheets from a Paulownia fortunei × tormentosa × elongata trihybrid clone. Also, the same ... -
