Abstract
Summary
Eucalyptus globulus wood samples were delignified in two-stage treatments carried out in media made
up of formic acid, water and hydrogen peroxide under selected operational conditions. The pulps were
subjected to Totally Chlorine Free (TCF) bleaching sequences. Alkaline treatments, oxygen delignification,
ozone stages and treatments with peroxyacids were assayed in order to reach the target values for
dissolving pulps. Under the best conditions, a fully bleached pulp (91.6% ISO brightness) with SCAN
viscosity of 649 ml/g and favourable molar mass distribution was obtained.
