High ratio of cellulose/water is very promising for industrial
application, meaning a high concentration of glucose solution
which is favorable for subsequent upgrading by chemical or biological
processes. The swelling/regeneration method is also suitable
for processing a large amount of cellulose hydrolysis. The yield of
glucose first increased with increasing cellulose amount and then
decreased till the concentration of cellulose reached 50 g/L.
58.53% yield of glucose was given in water in the presence of
15 g/L cellulose at 160 C for 10 min; and 29.1% yield of glucose
can still be obtained even at a high concentration of 50 g/L, where
up to 16.2 g/L of glucose solution is given.
