Organosolv pulping-vii - delignification selectivity of formic-acid pulping of eucalyptus-grandis
(ELSEVIER SCI LTD, 1994)
Eucalyptus grandis wood was ca. 80% delignified in 79-92% (v v-1) formic acid containing 0.22% (w v-1) HCl as a catalyst under reflux and mechanical stirring for 90 min. Pulps obtained under these conditions presented pulp ...
Simultaneous production of ethanol and kraft pulp from pine (Pinus radiata) using steam explosion
(ELSEVIER SCI LTD, 1995)
Radiata pine chips (Pinus radiata) were pretreated by steam explosion, for the simultaneous production of ethanol and pulp. Ethanol was produced fr om the depolymerized hemicellulose fraction recovered after the explosion, ...
