Following ideal bleaching, the removal of undesirable components present in the pulp, such as lignin and hexenuronic acids, is efficient, but at a low cost in the process. As this removal occurs differently, the sequence used should contain suitable ways for removal of these two chemical compounds. The high temperature acid hydrolysis (AHT) stage presents adequate conditions for the selec…
The quest for sustainable development opens up more and more space for research aimed at developing and obtaining nanomaterials obtained from sustainable sources, via sustainable processes, with applications for improving health and quality of human life, in remediating the environment and others. Nanocellulose has attracted a lot of attention as a component of new materials or advanced m…
In the bleaching process it is ideal that the removal of undesirable components present in pulp, such as lignin and HexA's, give an efficient manner, but at low cost in the process. As this removal occurs differently, the sequence used should contain suitable ways for removal of these two chemical compounds. The high temperature of acid hydrolysis (AHT) stage presents adequate conditions …
The search more environmentally viable and sustainable process, causes the pulp and paper industry to invest reducing number stages used in bleaching, order to reduce volume of effluents generated in process. Chlorine dioxide is commonly used in bleaching plants to be treated for a selective chemical reagent and quite effective in delignification cellulose pulp, besides generating a small…
The acid hydrolysis stage (AHT), used in bleaching sequences of pulp, is primarily engaged in the degradation hexenuronic acid, which if is present on paper can affect brightness reversion, among other factors. Despite benefit using acid hydrolysis stage, when it comes to lignin degradation the pH of pulp is not the most appropriate, because lignin is more reactive in alkaline medium. The…
