Preliminary Investigation of Pyrolysis Oil Upgrading Via Emulsification with Biodiesel
Chiaramonti, D., Rizzo, A.M., Peruzzi, N., Bonini, M., Fratini, E., Baglioni, P.
Fast pyrolysis of biomass is a thermochemical process for producing fuels and chemicals from renewable sources that gained the attention of the scientific community during the last decades. Significant progress has been made in the last years towards the lack of availability and consistency of biooil; nevertheless, the chemicophysical properties of crude biooil such as low pH, high viscosity, and immiscibility with diesel fuel still do not easily allow its direct use in power and heat generation. We report the preliminary results of emulsification of biooil with biodiesel in different amounts and with the help of various surfactants and cosurfactant as an upgrading path. The effect of emulsification of small amounts of biooil in biodiesel was investigated. Several commercially available nonionic surfactants were tested, and their effect on the stability of the produced emulsions was monitored.
