titleOfInvention | Method of producing lignocellulosic pulp from non-woody species |
abstract | High-yield chemimechanical lignocellulosic pulp is produced from non-woody species by cutting and screening the non-woody species, soaking them in an acidic aqueous solution preferably containing a chelating agent, treating the washed non-woody species with an alkaline peroxide solution containing a second chelating agent, and mechanical refining. To further increase the bleaching efficiency the non-woody species are impregnated with ozone or peracetic acid. The resulting pulp has a relatively high brightness while the consumption of peroxide is reduced compared to prior art processes. |
