A process for obtaining cellulose, hemicellulose and lignin from lignocellulose can be carried out in an environmentally friendly manner when it comprises the following steps: step a) wherein a lignocellulose from plant biomass is provided, step b) wherein the lignocellulose is brought into contact with a first mixture M1 containing water and an alkaline component, and a first suspension S1 forms, the first suspension S1 comprises a first solid F1 and a first liquid phase P1, wherein the first solid F1 contains a crude cellulose, and the first liquid phase P1 contains hemicellulose and lignin, and step c) wherein the crude-cellulose-containing solid F1 is brought into contact with a second mixture M2 containing formic acid and water and optionally acetic acid, and a second suspension S2 forms, the second suspension S2 comprises a second solid F2 and a second liquid phase P2, wherein the second solid F2 contains a pure cellulose, and the second liquid phase P2 contains hemicellulose and lignin.

The present invention relates to a process for treating pulp comprising a step, wherein the pulp is treated with distilled percarboxylic acid, such as distilled per-carboxylic acid (dPAA), and peroxide, such as hydrogen peroxide.

In some embodiments, a method may include treating pulp in pulp and paper mills. The methods may include providing a peracetate oxidant solution and generating a reactive oxygen species. The peracetate solution may include peracetate anions and a peracid. In some embodiments, the peracetate solution may include a pH from about pH 10 to about pH 12. In some embodiments, the peracetate solution has a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, the peracetate solution has a molar ratio of peracetate to hydrogen peroxide of greater than about 16:1. The peracetate oxidant solution may provide enhanced treatment methods of bleaching, brightening, and delignifying pulp fibers involving the use of peracetate oxidant solutions.

Process for the delignification and bleaching of pulp, comprising a first bleaching stage with hydrogen peroxide in the presence of a molybdate or tungstate in an acidic aqueous mixture; subsequent to the first bleaching stage, a second bleaching stage with hydrogen peroxide in an alkaline aqueous mixture; and, subsequent to the second bleaching stage, a third bleaching stage with hydrogen peroxide in the presence of a molybdate or tungstate in an acidic aqueous mixture.

The present disclosure relates to a process for extracting sugars from a pretreated lignocellulosic biomass. This process consists of contacting the pretreated lignocellulosic biomass with low charges of an aqueous peroxy acid (PA) solution to produce a liquid fraction (containing a small amount of lignin and hemicellulose degradation products) and a solid fraction containing cellulose, hemicellulose and lignin. The solid fraction can then be subjected to enzymatic hydrolysis with a variety of cell wall-degrading enzymes to produce a lignin-rich residue and a sugar solution that can be fermented to a variety of (bio)chemicals.

In some embodiments, a method may include reducing the microbial load in contaminated water of water recycle loops. These water recycling loops may include pulp and paper mills, cooling towers and water loops, evaporation ponds, feedstock processing systems and/or non-potable water systems. The methods may include providing a peracetate oxidant solution. The peracetate solution may include peracetate anions and a peracid. In some embodiments, the peracetate solution may include a pH from about pH 10 to about pH 12. In some embodiments, the peracetate solution has a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, the peracetate solution has a molar ratio of peracetate to hydrogen peroxide of greater than about 16:1. The peracetate solution may provide bleaching, sanitizing and/or disinfection of contaminated water and surfaces. The peracetate oxidant solution may provide enhanced separation of microbes from contaminated water.
