Transformation of oil palm mesocarp fiber to convertible materials in water at subcritical state

In this research, water at subcritical state was studied as an alternative way to breakdown oil palm mesocarp fibre (OPMF) by analysing their structural and compositional changes at different reaction temperature. High ion products of water in subcritical conditions and the dielectric constant...
