Abstract
A method for treating biomass including lignocellulosic polymers. The biomass is treated in a mixture of water with at least one oxidizing agent and steam at a temperature in a range of from about 130° C. to about 220° C. for a period from about 5 seconds to about 10 hours. The pH of the mixture is periodically measured for substantially an entire duration of the treating step. As necessary, based on the measured pH of the mixture, adjusting the pH of the mixture into a range of from about pH 4.5 to about pH 7.5 by adding a base to the mixture.
