Preparation and Properties of Nanocellulose from Organosolv Straw Pulp [PDF]

Nanoscale Research Letters, 2017
The object of this work is to present a study of nanocellulose preparation from organosolv straw pulp (OSP) and its properties. OSP was obtained through thermal treatment in the system of isobutyl alcohol–H2O–KOH–hydrazine followed by processing in the ...

Agricultural Residues as Raw Materials for Pulp and Paper Production: Overview and Applications on Membrane Fabrication

Membranes, 2023
The need for pulp and paper has risen significantly due to exponential population growth, industrialization, and urbanization. Most paper manufacturing industries use wood fibers to meet pulp and paper requirements. The shortage of fibrous wood resources

Changes in Nanoscale Porosity by Wet Pressing Pulps from Sugarcane Bagasse

BioResources, 2015
Nanoscale porosity is critical for cellulose reactivity and can be detrimentally affected by wet pressing. The present study evaluated how wet pressing reduced the nanoscale porosity of a set of pulps produced from sugarcane bagasse.

Organosolv Lignin as a Green Sizing Agent for Thermoformed Pulp Products

ACS Omega, 2022
The purpose of this study was to investigate the use of organosolv lignin as a sizing agent for thermoformed pulp products as a sustainable material with improved water resistance. For this purpose, an in-house-produced organosolv lignin from softwood (Norway Spruce) was mixed with bleached and unbleached chemi-thermomechanical pulp fibers. In addition,

Towards the Potential of Using Downstream-Separated Solvents as the Pulping Liquor of Upstream Lignocellulose Fractionation for Enhanced Acetone–Butanol–Ethanol Production

Fermentation
Developing efficient, clean, and sustainable lignocellulose pretreatment technologies is essential for second-generation biofuel production. In this study, we attempted to use downstream-separated binary acetone-water, n-butanol-water, and ethanol-water ...
