Enhancement of oil palm empty fruit bunch char by impregnation of pyrolytic carbon from tar vapor decomposition

This paper describes a technology for condensable vapor from pyrolysis (often referred to as “tar”) of oil palm empty fruit bunch, EFB, to be collected—by EFB char substrate—in the form of pyrolytic carbon to produce a value-added EFB char and to make EFB able to be utilized as a supplementary solid...
