Hydrogen peroxide and caustic soda: Dancing with a dragon while bleaching,TAPPI Journal December 2024
Peter W. Hart, Carl Houtman, and Kilby Hirth | TAPPI J. 12(7): 59(2013) - ABSTRACT: When hydrogen peroxide is mixed with caustic soda, an auto-accelerating reaction can lead to generation of significant amounts of heat and oxygen. On the basis of experiments using typical pulp mill process concentration and temperatures, a relatively simple kinetic model has been developed. Evaluation of these model results reveals that hydrogen peroxide-caustic soda systems are extremely sensitive to hydrogen peroxide:caustic soda ratio, transition metal contamination, and temperature. Small changes in initial conditions can result in a closed system becoming explosive. Analysis of model results was used to develop guidelines for safer application of hydrogen peroxide in a mill setting.

Production of high yield bleached hardwood kraft pulp: Breaking the kraft pulp yield barrier,TAPPI Journal December 2024
Author: Peter W. Hart | TAPPI J. 10(9): 37(2011) - ABSTRACT: A modified kraft pulping process has been developed that successfully breaks the traditional hard-wood kraft pulp yield barrier. The process produces fully bleached, high brightness hardwood kraft pulp with a yield of greater than 53% on wood. Details of the development and processing steps, along with various recovery cycle impacts, are discussed.
