A METHOD OF PREPARING BLEACHED PULP WITH HIGH YIELD BY FREE RADICAL CLEANNESS KRAFT PROCESS

摘要

A method of preparing bleached pulp with high yield by free radical cleanness kraft process, which includes providing electrons to the reactive medium in the electrochemical vessel by electrodes as the pH is subacidity. And put oxygen and/or nitrogen into the reactive vessel, and at the same time add chelating agent, cellulose protectant and free radical stabilizer to the reactive vessel. So as to field a great variety of free radical and to separate the lignin from it, thus bleached pulp is obtained.
