Optimization of delignification process from red meranti wood sawdust pretreated with acidified sodium chlorite

Delignification is a process to remove the lignin content from lignocellulosic biomass to increase hydrolysis efficiency. In other word, the process ensure cellulose parts are more accessible. In the present research, there were two objectives; i) to optimize the operating parameters of acidified so...

In the present research, there were two objectives; i) to optimize the operating parameters of acidified sodium chlorite pretreatment for delignification of RMWS, and ii) to characterize the RMWS that used as feedstock. The two significant variables, reaction time and ratio of sodium chlorite to sawdust were optimized using response surface methodolog and experiments were performed according to a central composite experimental design in order to enhance the delignification process as well as holocellulose recovery. The experimental design was expressed based on preliminary work and screening process using the combined severity, which ranged from 0.76 to 1.64 for chlorite solution and temperature range from 65°C to 85°C.
