| 摘要 |
<p>Oxidized white liquor is used as an alkali source in the delignification or bleaching of primary and secondary pulps by oxygen delignification, alkali extraction (E), oxygen alkali extraction (Eo), peroxide-enhanced alkali extraction (Ep), peroxide-enhanced oxidative extraction (Eop), peroxide bleaching (P), hypochlorite bleaching (H), ozone bleaching (Z), chlorine dioxide bleaching (D), or FAS bleaching. Oxidized white liquor is a replacement for sodium hydroxide as an alkali source in these processes, and the use of oxidized white liquor gives improved bleaching and delignification compared with the use of sodium hydroxide.</p> |
