Hardwood soda-AQ pulps are believed to be rich in benzyl sugar ethers (BSE) that can be partially cleaved by aqueous acidic treatments. The aim of this investigation was to evaluate the effect of acidolysis on final bleached brightness for kraft and

Four metal organic frameworks (MOFs) are being evaluated as possible catalysts for alkaline lignin oxidation. One aspect of the screening process is the oxidation of in-situ hardwood lignin by a high mole ratio of Cu, Fe, or Cu + Fe contained in the

The peroxymonocarbonate mono-anion (HCO4─) is generated when the bicarbonate anion is added to a H2O2 solution. The mono-anion is believed to have a pKa value of ca. 10 and as such would start dissociating to the di-anion (CO42─) at pH ca. 8. The

Sugar maple (Acer saccharum), aspen (Populus tremuloides), and white birch (Betula papyrifera) are three hardwoods that are widely used by the North American pulp and paper industry. Because of their abundance, these species are also likely to be use

In most native lignins, at least 50% of the phenylpropane (C(9)) units are involved in β-O-4 linkages. It was recently observed that ethylguaiacol (EG) was efficient at trapping coniferyl alcohol generated from the cleavage of uncondensed β-O-4 dim

Development of value-added products from any unutilized woody or non-woody material can play a vital role in economic development and also in forest resources conservation of any country. In this study, the suitabilities of planer waste and chips of

The carbohydrate composition of lignocellulosic biomass is normally obtained by the quantification of monomers after two stages of hydrolysis in H 2 SO 4 . A new two-stage hydrolysis protocol has recently been developed but so far only results for te

The range of xylan content reported for sugar maple ( Acer saccharum ) is wider than for most hardwoods. Credible values have been reported that range from less than 16 wt% to more than 19 wt% based on extractive-free wood. Carbohydrate composition o

Soda pulping catalyzed by anthraquinone (AQ) or 2-methylanthraquinone (MAQ) can produce hardwood chemical pulps similar to kraft pulps in all respect but for bleachability. Results accumulated in our laboratory suggest that the residual lignin in pul

The positive aspects of the non-sulfur soda/anthraquinone (SAQ) process are mostly tied to improved energy efficiency while lower pulp brightness after bleaching is its most significant drawback. A credible method that quantifies bleachability as wel
