|Title:||Delignification of bagasse with acetic acid and ozone. Part 1. Acetic acid pulping|
Sanjuan D, R.
|Abstract:||Two-stage delignification of sugarcane bagasse with acetic acid and ozone was investigated. The better pulp was obtained pulping bagasse in aqueous solution of acetic acid (80% volume) at 145�C during 60 min. The liquor/bagasse ratio (L/B) was 10:1 and the kappa number was 44; it fell to 10 in the ozone stage due to selectivity of acetic acid medium. Pulp reaches a brightness of almost 70% Elrepho and the strength properties are similar to those of soda pulps without refining and better than acetosolv pulps.|
