Preparation Of Novel Cellulose Membrane From Hybrid Giant Napier

Traditional pulping processes are typically used for making pulp from wood fibers. However, these processes are energy-intensive, require large capital investments, and contribute to air and water pollution. Technologies are currently in development that would reduce the environmental impact of kraft pulping. The above reasons have raised the need for new plants that use processes requiring modest investments to obtain quality products at a low cost while preserving the environment, reducing chemical, water and energy consumption, increasing the yield of wood raw materials and using alternative materials such as agricultural residues.In this article, hybrid giant napier, an agricultural residue, was chosen as raw material for pulping process and hybrid giant napier cellulose was prepared with ethanol pulping after steam explosion pretreatment. Ionic liquid [bmim]Cl and water were used as solvent and coagulator to make regenerated hybrid giant napier cellulose membrane.
