Effects of the water quantity on the solventless TEOS hydrolysis under ultrasound stimulation
(Kluwer Academic Publ, 2000-01-01)
The acid hydrolysis under ultrasound stimulation of solventless tetraethoxysilane(TEOS)-water mixtures was studied at 40 degrees C, by means of a heat flux calorimetric method, as a function of the initial water/TEOS molar ...

Hidrólise ácida e enzimática de casca de arroz usando tecnologias alternativas
(Universidade Federal de Santa MariaBREngenharia de ProcessosUFSMPrograma de Pós-Graduação em Engenharia de Processos, 2014-03-31)
Rice husk is a fairly abundant agro-industrial waste in the state of Rio Grande do Sul, hence the same has been suggested and studied to be used as in lignocellulosic hydrolysis to produce fermentable sugars material. ...
Xylanase and β-xylosidase from Penicillium janczewskii: Purification, characterization and hydrolysis of substrates
(2016-09-01)
Background: Xylanases and β-D-xylosidases are the most important enzymes responsible for the degradation of xylan, the second main constituent of plant cell walls. Results: In this study, the main extracellular xylanase ...

Optimization of acid hydrolysis from the hemicellulosic fraction of Eucalyptus grandis residue using response surface methodology
(Elsevier B.V., 2007-01-01)
Biotechnological conversion of biomass into fuels and chemicals requires hydrolysis of the polysaccharide fraction into monomeric sugars. Hydrolysis can be performed enzymatically and with dilute or concentrate mineral ...
Kinetics of autocatalytic acid hydrolysis of cellulose with crystalline and amorphous fractions
(SPRINGER, 2010)
The acid hydrolysis of cellulose with crystalline and amorphous fractions is analyzed on the basis of autocatalytic model with a positive feedback of acid production from the degraded biopolymer. In the condition of low ...
Solid-state hydrolysis of postconsumer polyethylene terephthalate after plasma treatment
(2013-02-05)
Plasma treatments were applied on the surface of postconsumer polyethylene terephthalate (PET) bottles to increase their wettability and hasten the subsequent hydrolysis process. Sixty-four treatments were tested by varying ...
