Abstract

Delignifikasi bagi pulpa soda-AQ tandan kosong kelapa sawit (Elaeis guineensis) dengan oksigen dihadkan pada 38% demi mengelakkan degradasi selulosa yang serius. Untuk meningkatkan keberkesanan bagi delignifikasi oksigen (peringkat O), sejumlah kecil hidrogen peroksida (H2O2) bersama atau tanpa antrakuinone (AQ) ditambahkan semasa oxygen delignifikasi dan dikenali sebagai delignifikasi oksigen diperkuat dengan hidrogen peroksida (peringkat OP), manakala dengan pernambahan AQ dikenali sebagai peringkat OP dengan pembantuan-AQ. The delignification of oil palm (Elaeis guineensis) empty fruit bunch fibres soda-AQ pulp by oxygen is limited to 38%, to avoid substantial cellulose degradation. To enhance the effectiveness of oxygen delignification (O stage), small amounts of hydrogen peroxide (H2O2) with and without anthraquinone (AQ) are added during oxygen delignification, which are known as the hydrogen peroxide reinforced oxygen delignification (OP stage) and AQ-aided OP stage respectively.
