WebKraft pulping is considered as most dominant process to obtain lignin from the lignocellulosic biomass. In pulping process via kraft method, aqueous sodium hydroxide along with sulfides at a temperature range of 423–453 K for 2 h to separate lignin from the cellulose under high pH condition [2]. WebPulping Technologies Mechanical Pulping Processes There are six basic mechanical pulping processes: 1 ) stone groundwood, 2) refiner, 3) thermomechani- cal pulping, 4) chemical mechanical, 5) defibrated or exploded pulping, and 6) recycled paper.2 Mechani- cal pulping is generally used with softwoods be-
