Organosolv
pulping processes are able to generate liquid hemicellulose
fractions with a low cellulose and lignin content. Utilization of
such streams is promising for production of high-value chemicals.
In this study, on the basis of three reaction models, kinetics of
an aqueous organosolv hemicellulose and d-xylose conversion
into furfural was examined at temperatures between 160 and 200 °C
using a continuous tube reactor. Furthermore, furfural degradation
was investigated to consider the self-polymerization. Results were
compared with previous studies and differences are discussed. Kinetic
models showed slight differences for d-xylose conversion
and stronger deviations for furfural formation. Overall, model 3,
which includes the formation of a xylose intermediate, showed the
best performance concerning the experimental results. Differences
between d-xylose and organosolv hemicellulose conversion
can be attributed mainly to sugar oligomers.
