| Abstract: | The technology of urea-potassium hydroxide for pretreating wheat straw was studied in this paper.The dosages of urea and potassium hydroxide,temperature,time and liquor ratio were investigated in order to produce a chemi-mechanical pulp which the unscreened yield of the pulp was beyond 65%.The results shown that the chemi-mechanical unscreened yield was 65.72% when the dosages of urea and potassium hydroxide were 12%,8% respectively,and pretreatment temperature,heating time and keeping time at the high temp... |
