Abstract
The bio-oil from fast pyrolysis of biomass cannot be used effectively as engine fuel because of its high corrosiveness and instability mainly due to substantial amounts of organic acids and reactive aldehydes. In this paper treatment of acids in the bio-oil was focused and esterification with different catalyst to convert the acids. Synergistic interactions among reactants and products were determined. Acid-catalyst removed water and drove the esterification reaction formation equilibria toward ester products. Effect of Amberlyst-15 on different acids present in the bio-oil was carried out and characteristics properties of bio-oil shown after treatment were improved. Catalyst characterization was carried and observed that carbon deposition on the surface of catalyst reduces the activity of the Amberlyst-15. The catalysts with high surface area, large pore size distribution, and strong acid sites may be beneficial for the esterification reaction.
