Residual acid effect on oxygen delignification
(2016-06-01)
This work has aimed to evaluate the effect of usage of residual acid from the chemical plant of chlorine dioxide production as a #owing part of oxidized white liquor (OWL). Delignification processes were accomplished using ...
EFFECT OF KRAFT PULPING TEMPERATURE AND ALKALINITY ON EUCALYPTUS ECF BLEACHING
(Editura Acad Romane, 2016-10-01)
The effects of eucalyptus kraft pulping conditions on subsequent bleaching were investigated. Three samples of industrial eucalyptus chips underwent haft pulping with different alkalinities and hexenuronic acid (HexA) ...
Mass balance of pilot-scale pretreatment of sugarcane bagasse by steam explosion followed by alkaline delignification
(ELSEVIER SCI LTDOXFORD, 2012)
Five pilot-scale steam explosion pretreatments of sugarcane bagasse followed by alkaline delignification were explored. The solubilised lignin was precipitated with 98% sulphuric acid. Most of the pentosan (82.6%), and the ...
Steam explosion pretreatment reproduction and alkaline delignification reactions performed on a pilot scale with sugarcane bagasse for bioethanol production
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
This work was focused on the steam explosion pretreatment reproduction and alkaline delignification reactions on a pilot scale for the ethanol production, through different varieties of natural sugarcane bagasse, pretreated ...
Pré-tratamento organossolve do bagaço de cana-de-açúcar para a produção de etanol e obtenção de xilooligômeros
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2011-03-29)
Sugarcane bagasse is an abundant lignocelulosic byproduct, due to the high ethanol production from sugarcane juice, which turns this residue an attractive alternative for obtaining cellulosic ethanol and other products of ...
Evaluation Of Alkaline Delignification (naoh) Of Açaí Seeds (eutherpe Oleracea) Treated With H2so4 Dilute And Effect On Enzymatic Hydrolysis
(Italian Association of Chemical Engineering - AIDIC, 2015)
Polypropylene/chemically treated coir composites: optimizing coir delignification conditions using central composite design
(2018)
© 2017, Springer Science+Business Media B.V., part of Springer Nature.The effect of alkaline treatment of coir on polypropylene/coir composite properties was investigated, using a two-factor central composite design where ...
Integrated dynamic model of the alkaline delignification process of lignocellulosic biomass
(Universidad Nacional de Colombia Sede Medellín, 2011)
Although in the public literature there are several studies that describe models of alkaline delignification, they were originallydeveloped for the paper industry, and do not include the effects of important operating ...
