Alcell process
Organocell uses two-stage organosolv with roughly 50% methanol solutions. Sodium hydroxide is added in the second stage at a loading of 30% w/w of the dry wood. The lignin from the second stage is isolated by adding phosphoric acid until a pH of 4.0 is reached. The Alcohol Pulping and Recovery (APR) process treats wood in 3 stages, each using increasingly cleaner solvent. The important process parameters are extraction time, temperatur… WebMar 7, 2008 · The ALCELL ® process is an ethanol-based autocatalyzed solvent pulping technology which is being developed by Repap Enterprises Inc.
