摘要：
A multi-function process for the separation of cellulose fibers (9) from the other constituents of lignocellulosic biomass such as found in grasses, agricultural waste, and waste paper with application in the preparation of feedstocks (1) for use in the manufacture of paper, plastics, ethanol, and other chemicals. This process minimizes waste disposal problems since it only uses only steam (6), water, and oxygen at elevated temperature in the range of 180 OC to 240 OC for 1 to 10 minutes plus a small amount of chemical reagents (23) to maintain pH in the range 8 to 13. An energy recuperation function is important to the economic viability of the process.
