ABSTRACT
The
liquefaction of oil palm empty fruit bunch (EFB) in phenol was carried out in the presence of sulfuric acid as a
catalyst in the reflux condenser system. The effect of initial phenol input and EFB on liquefaction reaction was
investigated by measuring the reaction yield, EFB residue and combined phenol. The initial ratio of phenol to EFB has the greatest influence on the residue and reaction yield.
The liquefaction products consist of some liquid by products with high amount
of OH groups. The amount of this
byproduct was 0.5 time of the solid product (phenolic resin).
Keywords:
Empty fruit bunches; liquefaction; phenol; sulfuric acid
ABSTRAK
Pencecairan serabut tandan kosong kelapa sawit(EFB) dalam fenol telah dilakukan dengan kehadiran asid sulfurik sebagai mangkin dalam sistem kondenser refluks. Kesan kemasukan awal fenol dan EFB terhadap tindak balas pencecairan telah dikaji dengan pengukuran hasil tindak balas, bakiEFB dan fenol tergabung. Hasil kajian menunjukkan nisbah awal fenol terhadap EFB memberi kesan terhadap baki dan tindak balas hasil. Bahan pencecairan mengandungi beberapa bahan sampingan cecair dengan kehadiran kumpulan OH yang tinggi. Jumlah hasil sampingan bahan tersebut adalah 0.5 kali hasil pepejal (resin fenol).
Kata kunci: asid sulfurik; fenol; pencecairan; serabut tandan kosong
