A neural fuzzy model applied to hydrogen peroxide bleaching of non-wood soda pulps
(2012)
Article
Accés obertA neural fuzzy model was used to examine the influence of pulp bleaching variables of empty fruit bunches from oil palm (EFB) and Hesperaloe funifera, such as soda concentration (0.5-3%), hydrogen peroxide concentration ... -
Assessing the environmental impact of biobleaching: effects of the operational conditions
(2012-01)
Article
Accés restringit per política de l'editorialThe environmental impact of enzyme bleaching stages applied to oxygen-delignified eucalypt kraft pulp was assessed via the chemical oxygen demand (COD), color, absorbance spectrum, residual enzyme activity and Microtox ... -
Effect of commercial xylanases applied at extreme conditions in a eucalyptus pulp mill
(2012-10)
Article
Accés restringit per política de l'editorialIn this study, we examined the effect of treating eucalyptus pulp with various commercial xylanases to identify the most effective enzyme for use under the industrial bleaching conditions used at the Jacareí mill of the ... -
Influence of enzyme and chemical adsorption on the thermal degradation path for eucalyptus pulp
(2013)
Article
Accés restringit per política de l'editorialChanges in thermal degradation path of eucalyptus pulp support enzymes (laccase from Trametes villosa) and chemicals (Tris–HCl or tartrate–tartaric buffer) adsorption on cellulose during biobleaching, thereby increasing ... -
Use of cyclic voltammetry as an effective tool for selecting effcient enhancers for oxidative bioprocesses: importance of pH
(American Chemical Society (ACS), 2013-01-04)
Article
Accés restringit per política de l'editorialSeven natural phenols and two synthetic compounds were evaluated by means of cyclic voltammetry as enhancers for the oxidation of the lignin model compound veratryl alcohol (VAl) and a sulfonated lignin (SL). Their ...
