Abstract
Furfural is a biomass derived-chemical that can be
used to replace petrochemicals. In this study, dilute sulphuric
acid hydrolysis was used for hemicelluloses secession from birch
wood. The reaction was investigated at different biomass
treatment times (10-90 min, increasing it by 10 min). We found
that the greatest amount of furfural 1.4-2.6%, which is 9.7-17.7%
from theoretical possible yield, was formed in the first 30 min of
the beginning of birch wood pentoses monosaccharide
dehydration, but the greatest yield of furfural 10.3%, which is
70.0% from the theoretical yield, can be obtained after 90 min.
Given that furfural yield generally does not exceed 50% from the
theoretical amount, the result can be considered as very good
