Preparation and characterization of biopolyol from liquefied oil palm fruit waste: part 2 [PDF]

open access: yes, 2016
Oil palm fruit waste (OPFW) was conducted using polyhydric alcohol (PA) as liquefaction solvent with H2SO4 in three different OPFW/PA ratio (1/2, 1/3 and 1/4). During the liquefaction, cellulose, semi-cellulose and lignin are decomposed, which results in
