1. A method for treating biomass comprising:
adding gaseous ammonia at an elevated temperature to a reaction vessel containing biomass, wherein the reaction vessel is operated under a pressure of about 100 psi to about 1000 psi; allowing the gaseous ammonia to condense on the biomass and react with water present in the biomass, to produce a pretreated biomass, wherein the reaction vessel pressure is released over a period of greater than two minutes; and removing residual ammonia present in the reaction vessel. |
