Phenolic rich components identification of heavy oil fractions of biomass pyrolytic oil for epoxy resin binder

摘要

Identification and assessment of phenol and phenolic rich components of heavy oil fractions of biomass pyrolytic oil were conducted. The original bio-oil used for this study was derived from the pyrolysis of empty fruit bunch (EFB). It was separated into water soluble (light oil) and water insoluble (heavy oil) components by mixing it with water at 2:1 V/V ratio under ambient condition with vigorous stirring using centrifuge for 30mins. The raw bio-oil and the heavy oil fractions were later characterized using Fourier Transform Infra-Red (FTIR) and Gas chromatography-Mass spectroscopy (GC-MS) techniques in order to identify the function groups present and their compositions. The GC-MS results for the heavy oil indicated a high concentration of phenol and phenolic components, which was strongly supported by the presence of OH group (characteristic of phenol) from FTIR analysis. Utilization of bio-oil which was known to have a significant amount of phenol and phenolic rich components for phenolic, novolac or epoxy resin manufacture would significantly reduce the cost and negative environmental effects of the fossilbased resins.
