The Use of Demolition Wood in Papermaking [PDF]

open access: yes, 1996
The reason for this study came from three factors affecting the paper industry as well as society as a whole. These factors are decreasing landfill space, increasing tipping fees, and increasing demands for alternative fiber sources. In the United States,

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Three Stage Bleaching of Recycled Fibers Containing 30% Groundwood [PDF]

open access: yes, 1978
A three stage bleaching sequence for a mixture of recycled chemical and groundwood fibers was investigated for maximum brightness increase. The three stages consisted of a reducing or color stripping stage, an oxidizing stage, and last a mild alkaline ...

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

open access: yesIntegrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

High pressure pre-treatments promote higher rate and degree of enzymatic hydrolysis of cellulose [PDF]

open access: yes, 2011
The effect of high pressure (HP) pre-treatments on the subsequent enzymatic hydrolysis of cellulose from bleached kraft Eucalyptus globulus pulp by cellulase from Tricoderma viride was evaluated. Pressure pre-treatments of 300 and 400 MPa during 5–45 min,

Photoluminescence Properties of Lignin With a Genetically Introduced Luminophore in a Transgenic Hybrid Aspen That Overproduces Feruloyl‐CoA 6′‐Hydroxylase

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Lignin, a major cell‐wall component of woody biomass, exhibits photoluminescent (PL) properties. Controlling the intensity and colour of the PL is essential for producing lignin‐based value‐added materials. Herein, we modify the PL properties of lignin via genetic engineering of novel luminophore structures. Feruloyl‐CoA 6′‐hydroxylase (F6′H1)

The adsorption of adsorbable organic halide onto biological solids : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Technology in Environmental Engineering [PDF]

open access: yes, 1994
Chlorinated organic molecules may be removed from wastewaters by adsorption onto the biomass present in biological treatment systems. This study assessed the adsorption onto biological solids of Adsorbable Organic Halide (AOX) from two New Zealand kraft ...

Techno-economic analysis of energy efficiency measures in a pulp mill converted to an ethanol production plant [PDF]

open access: yes, 2009
A conceptual ethanol production plant, based on conversion of a kraft pulp mill, has been studied. The process uses softwood as raw material, alkaline pre-treatment combined with delignification, and biochemical conversion of sugars to ethanol (i.e ...
