Abstract

This research aimed to examine the upgrading of the sisal residue bio-oil from the relations between process conditions of the fast pyrolysis and the properties of the fluid. The bio-oil was produced in a pilot unit with a fluidized bed reactor by varying the nitrogen flow rate, biomass mass flow, temperature, and pressure. Overall, the bio-oil composition was intensely dependent on the process parameters. The pressure at the lowest value was the best condition for obtaining the bio-oil in high yield (up to 17 wt%), with the highest monomer yield (44.51 wt%) and the lowest O/C ratio (0.11). The characterization techniques applied revealed remarkably distinct characteristics between the bio-oil of sisal residue and other biomass. The sisal residue bio-oil had a lower oxygen and water content, higher thermal stability, higher degree of depolymerization, and a higher yield of aliphatics, naphthalenes, and alkylphenols.
