The process involves (a) an optional first step of treating the substrate with an aqueous alkali solution containing 1 to 20 % by weight, based on dry substrate, of a base at 20 DEG to 100 DEG C to swell and remove base soluble materials from the substrate; (b) separating the substrate and optionally washing it with water; (c) uniformly wetting the substrate with an aqueous alkaline solution containing 1 to 20 wt. % of base, based on dry substrate, to form a slurry, placing the slurry in a pressure vessel which is pressured with oxygen gas to 20 to 300 psig (138 to 2070 kPa) for 5 to 180 minutes at a temperature of 50 DEG to 150 DEG C to delignify the substrate, separating the delignified susbstrate from the lignin containing extract solution; (d) optionally bleaching the delignified substrate, preferably with an alkaline aqueous hydrogen peroxide solution; and (e) recovering the delignified substrate. Optionally more than one oxygenation step can be used with the substrate being separated from the oxygenation-extraction medium between oxygenation steps.

Abstract: The process of the present invention relates to a substantially sulfur free process for the manufacturing of a chemical pulp with an integrated recovery system for recovery of pulping chemicals. The subject process is carried out in several stages involving physical and chemical treatment of lignocellulosic material in order to increase accessibility of the lignocellulosic material to reactions with an oxygen-based delignification agent. Spent cellulose liquor comprising lignin components and spent chemical reagents is fully or partially oxidized in a gas generator wherein a stream of hot raw gas and a stream of alkaline chemicals and chemical reagents is formed for subsequent recycle and reuse in the pulp manufacturing process.
