The effects of hot oil treatment process on the chemical, colour and strenghth properties on 15-year-old cultivated acacia hybrid

The effects of hot oil treatment on the chemical, colour and strength properties of 15-year-old cultivated Acacia hybrid were investigated. Logs of A. hybrid were harvested and cut at the bottom, middle and top sections. The wood sections were treated in the hot oil treatment process using palm oil...

Holocellulose and celulose degraded with the increasing of treatment temperature and duration of heating exposure, while lignin showed the increment in content through this treatment.
