Softwood pulp is more recalcitrant toward enzymatic hydrolysis than hardwood or nonwood pulps. Pulps of various kappa numbers were prepared from loblolly pine chips by kraft cooking, which was followed by delignifying with oxygen/NaOH, chlorine dioxide, or ozone to lower lignin levels. These pulps w...
