Continuous countercurrent pretreatment of lignocellulose with anthraquinone prior to pulping |
| abstract |
Lignocellulose is treated with an alkaline pretreatment liquor containing anthraquinone or other pretreatment agent in a continuous process in which the lignocellulose and pretreatment liquor flow countercurrently. The pretreatment agent is substantially soluble in the pretreatment liquor introduced into the pretreatment zone and is substantially insoluble in the pretreatment liquor withdrawn from the pretreatment zone, with the result that the pretreatment agent is effectively recycled within the pretreatment zone. |
