A method for processing lignocellulosic precursors that includes the following steps:
A. provide a suitably sized lignocellulosic precursor with less than 25% moisture content;
B. pack a hydrothermal processing vessel with lignocellulosic precursor, such that the density of lignocellulosic precursor in the hydrothermal processing vessel is between 1 and 3 times the free flow density;
C. subject the lignocellulosic precursor in the hydrothermal processing vessel to steam below 1×10 7 Pa (100 bar) for up to 10 minutes;
D. slowly reduce the pressure to between 1×10 6 Pa and 2×10 6 Pa (10 and 20 bar);
E. explosively decompress to ambient pressure;
and then dry the resultant lignocellulosic product to below about 15% moisture content. |
