Southern pine oxygen delignified pulps produced in a Berty throughflow reactor: How to obtain the highest degree of delignification while maintaining pulp yield and quality

Originally published in March 2012 issue of TAPPI Journal, this unique study employs a Berty through-flow reactor – a technology traditionally used for catalytic studies in the petrochemical industry – to show how environmentally-friendly oxygen delignification technology can attain >60% delignification without impacting the strength and physical properties of fibers. Unlike batch reactors, the Berty reactor keeps alkali concentration low and uniform through a continuous resupply, allowing a higher degree of delignification without cellulose damage. Application of this technology opens possibilities similar to injection of white liquor at different locations in kraft cooking, and a patent was recently filed for a version of this technology, with a potential to influence current oxygen delignification reactor design.
