Abstract

In order to obtain the optimum conditions for preparing SEMI-CHEMICAL PULP form BAGGASSE using ethanol - caustic soda ORGANOSOLV PROCESS, depicted BAGGASSE (wet method) was prepared from pars pulp and paper mill , Khozestan province. Firstly, the anatomical and chemical characteristics of BAGGASSE were evaluated. The averages of fiber length and diameter, cell lumen, and cell wall thickness (120 fibers) were determined 1.53 mm , 21.76 m ,9.58 m , and 6.07 m respectively. Chemical composition of BAGGASSE (the average of 3 experiments) were 55.33% cellulose, 21.20% lignin, 9.58% extractives and 21.17% ash. The variables in pulping of baggase were as flowing a) Ethane (weight percent):30,40,60,70 b) Cooking liquor to BAGGASSE (l/w):8,10,12,15 c) Cooking time (minutes):15,30,45,60 d) Cooking temperature (C°): 145,165 ,175,185,195 e) Caustic soda ( weight percent):0,1,3,5,7 In order to evaluate the effect of each variable, the other parameters were kept unchanged and then, on the basis of the pulp yield and lignin content of the pulp, the suitable conditions for pulping was determined. Then, the yield, lignin content and freeness of the pulp sample were measured using three repeats and the results were statistically analyzed using completely accidental plan. The pulping conditions were tailored in such a way that the yield of the produced pulp is placed in the range of SEMI-CHEMICAL PULPs.
