The products obtained from the slow pyrolysis of palm oil EFB
in the biochar facility are biochar, syngas and bio-oil. The biochar
production efficiency is 20%, i.e. 1 t of EFB delivers 0.2 t of biochar.
In addition, 0.3 t of syngas and 0.025 t of bio-oil are obtained as
byproducts from each ton of EFB. The biochar produced is composed
of carbon (C), nitrogen (N), ash and water. Biochar also produce
volatile matter which is material with evaporates readily at normal
temperature, pressure and vaporized with value of 41% as shown
in Table 4.
