Abstract: Three pulp mills in North America using 50% hydrogen peroxide have suffered explosions of pumps, mixers, and tanks. In two instances, alkali-catalyzed decomposition of peroxide is implicated in the explosion. Although many mechanical pulping facilities use hydrogen peroxide to bleach pulp, no &-catalyzed explosions have been reported. This research uses a kinetic model of peroxide decomposition to explain why the peroxide bleaching process used for mechanical pulps has lower risks than processes used to bleach chemicalpulps.
