Catalytic Delignification of Cellulose Fibers by Hydrogen Peroxide in Presence of Polyoxometalates

摘要

Peroxide delignification of cellulose fibers in acid medium in presence of polyoxometalates as catalysts was studied. The effects of the hydrogen peroxide concentration, the catalyst nature, and the addition of the alkali processing stage on the process of delignification of leafy and coniferous celluloses were investigated.
