Growing stock of forest in Korea is considerably lower than any other developed countires. This is closely associated to low self-sufficiency of woods for pulp. Nevertheless, woods generated from the National Forest Management Operation have been mostly used to make wood pellets. Such woods must be allocated to produce value-added products like pulps, instead of wood pellet. Wood pellets can be manufactured from lignocellulosic raw materials such as corn stalk, bark, leaves, soy bean stalk, PKS and so on. Then new technology like torrefaction may be applied to improve heating efficiency of pellets made of such lignocellulosic biomass.

This study was to develope a novel automatic system for measuring Stöckigt sizing degree and contact angle at a time. The newly developed system could get reproducible results through automation of all procedures including liquid dropping, image acquisition and measurement of both Stöckigt sizing degree and contact angle. For the Stöckigt sizing test, the automatic system could measure sizing degree with more definite differences according to different dosage of AKD, compared to the conventional methods.

This study investigated softening effect of softwood chips according to different pulping conditions for CTMP. The amount of both sodium sulfite and sodium hydroxide played a vital role in softening wood chips. Pulping temperature was also a key factor to influence penetration of pulping liquor to wood chips.
