Acetylation Treatment for the Batch Processing of Natural Fibers: Effects on Constituents, Tensile Properties and Surface Morphology of Selected Plant Stem Fibers

open access: yesFibers, 2020
This work was on the comparative evaluation of the property effects obtainable when acetylation is applied to parts of selected agro fibers that are obtainable within common localities. The fibers were subjected to different concentrations of acetylation

Modificação das propriedades das fibras de curauá por acetilação Modification of the properties of curauá fibers by acetylation

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2011
Nos compósitos cimentíceos as fibras vegetais podem sofrer vários graus de degradação quando expostas ao ambiente alcalino. O meio alcalino degrada os componentes macromoleculares das fibras, principalmente pela solubilização da lignina e a desfibrilação

Analysis of hollow fiber bioreactor wastewater treatment [PDF]

open access: yesBiotechnology and Bioengineering, 1990
A mathematical model describing anaerobic biodegradation of acetate in an HFBR is presented here. The model considers the cylindrical geometry of hollow fibers and the nonlinear Monod kinetics that are characteristic of biodegradation. The results of the numerical solution of the model are used to predict the results of a planned benchscale study of ...
