At present, the papermaking industry generally uses chlorine or chlorine dioxide as a lignin-removing bleach, but the waste generated by the chlorine process contains environmentally harmful dioxins, and the chlorine dioxide process has high costs and high energy consumption.
American scientists first used a compound containing tungsten and molybdenum as a catalyst to pretreat wood pulp, and then used oxygen to bleach wood pulp. This technology solves the problem that oxygen cannot bleach wood pulp with low lignin concentration.
However, some experts believe that although this technology can reduce environmental pollution, commercialization must overcome some difficulties. For example, the heavy metals contained in the catalyst may pose a potential threat to the environment, and the equipment required for production is also relatively expensive.
