Unbleached softwood kraft pulp was subjected to low consistency oxygen bleaching.

The transition metal ions, such as Cu 2+ 、 Fe 3+ 、 Mn 2+ , not only effect the brightness of unbleached pulp, but also catalyze the radical reaction during oxygen bleaching.

The oxygen bleaching of magnesium-based sulfite pulp was conducted.

The application of a new activator TA-116 for oxidation bleaching process at lower temperature and pH value;

By application of cellulase in the process of oxidation bleaching of alenconnes,the promotion of fabric bleaching and the influence of fabric stiffness and strength are studied.

Changes of lignin structure during oxygen delignification by pyrolysis-gas chromatography-mass spectrometry;

In this article,it was mainly introduced the application of polyoxometalates in catalyzed oxygen delignification,included the researches of it in this ten years,the catalysis of POM in oxygen delignification and the elements which influenced it.

This paper studied the TCF bleaching of rice straw ammonium sulfite pulping, which contains of oxygen-alkali bleaching, acid treatment and hydrogen peroxide bleaching.

To produce high strength pulp with high consistency ozone bleaching for lowering effluent discharge;

A research on ozone bleaching of acacia in the sulfate pulp TCF process;

Kinetics studies of the ozone bleaching modal of the high consistency pulp;
