Abstract

Manufacture of high-yield paper pulp from wood chips. The process consists in successively treating the chips, before grinding, with a solution containing at least one reducing agent, and then with an alkaline hydrogen peroxide solution. Application to the manufacture of paper pulp with a high degree of whiteness and good mechanical characteristics.
