| 摘 要： | INTRODUCTIONChina is the country that produces the largest amount of wheat-straw pulp in the world. In North China, wheat-straw is used as the main row material for pulping. At present, the dominating pulping method of straw-wheat is soda-AQ. This method has many drawbacks. Its yield is difficult to reach 40%, its original pulp has low brightness (lower than 30%SBD), and its bleachability is also low. Three-stage bleaching sequence (CEH) is needed to obtain high brightness pulp. It c… |

| Abstract: | A study on alkaline sulfite anthraquinone pulping of wheat straw indicated that the addition of formaldehyde could improve fine pulp yield effectively, enhance brightness of unbleached pulp, and decrease kappa number. Finally, the optimum conditions of this process were formed. |
| Keywords: | ASF-AQ optimum process conditions fine pulping yield brightness kappa number |
