Published in 2018 at "Cellulose"

DOI: 10.1007/s10570-018-2172-x

Abstract: We recently found that subsequent treatments of hardwood kraft pulps with a tertiary amine (DABCO; 1,4-diazabicyclo[2.2.2]octane) catalyzed hypochlorous acid (Hcat), ozone (Z) and hydrogen peroxide (P) may provide full brightness with low chemical dosages in… read more here.

Published in 2018 at "Industrial Crops and Products"

DOI: 10.1016/j.indcrop.2018.08.071

Abstract: Abstract Pre-hydrolysis liquor (PHL) from the kraft-based dissolving pulp process contains large amounts of hemicelluloses and their degradation products, which makes it a promising candidate for the production of xylose or xylooligosaccharides (XOS). However, it… read more here.

Published in 2021 at "Journal of environmental management"

DOI: 10.1016/j.jenvman.2020.111891

Abstract: We introduce high frequency pulsed electrodialysis (hf-pED) to process the acidic filtrate of a Kraft pulp bleaching stage, tested in a pilot trial. Compared with conventional electrodialysis, hf-pED at 2,000 Hz allows a reduction in operational… read more here.
