Investigation on Neutral Sulfite Semi-Chemical Pulping of Reapseed (Canola) Residues

Neutral sulfite semi chemical pulping of Canola residues has been investigated. Canola residues collected from research farm at Agriculture and Natural Resources, University of Tehran, in Karaj. Chemical composition of Canola residues including cellulose, lignin, extractives soluble in ethanol-aceto...
