Preparation and characterization of biopolyol from liquefied oil palm fruit waste: part 1

摘要

Liquefaction is known to be an effective method for converting biomass into abiopolyol. The biomass liquefaction of oil palm fruit waste (OPFW) in the presence ofliquefaction solvent/polyhydric alcohol (PA): Ethylene glycol (EG), polyethylene glycol 400(PEG400) and glycerol using sulfuric acid as catalyst was studied. For all experiments, theliquefaction was conducted at 150 Celsius and atmospheric pressure. The mass ratio of OPFW toliquefaction solvents used in all the experiments was 1/2, 1/3 and 1/4. The results revealed thatalmost 50% of the oil palm fruit waste converted into liquid product within 2 hours at 150°Cwith OPFW/PA ratio of 1/4. Biopolyol produced under different condition showed viscositiesfrom 210 to 650 Pa.s. The result in this study may provide fundamental information onintegrated utilization of oil palm fruit waste via biomass liquefaction process.
