Abstract

Research has been conducted to study the effect of NaOH concentration, cooking temperature and cooking time on the production of pulp from Rami stalk using soda process. The use of Rami as raw material under study was because availability of wood as raw material for pulp is getting lesser by time, whilst Rami stalk may be a good substitute for it. Large stock of NaOH available in the market is the cause of the use of this chemical for the study. The range of variables studied were : NaOH concentrations at 5-15%, cooking temperatures of 100-120oC, and cooking time of 60-180 minutes. Analyses of the product was done for percent yield of the pulp produced, concentration of cellulose in the pulp, and lignin content in the pulp. Results show that in the range of values studied, the three variables, NaOH concentration, temperature of cooking and cooking time, did not give any significant effect on the amount of pulp produced and the concentration of cellulose in the pulp, whilst they give proportional effect on the lignin content in the pulp. Best condition with smallest lignin concentration of 6.83%, was found at NaOH concentrations of 5%, cooking temperature of 105oC,  and cooking time of 60 minutes.
