The chemical and physical properties of raw biooils prevent their direct use in combustion engines. We processed raw pyrolytic biooil derived from chicken manure to yield a colorless refined biooil with diesel qualities. Chemical characterization of the refined biooil involved elemental and several spectroscopic analyses. The physical measurements employed were viscosity, density and heat of combustion. The elemental composition (% wt/wt) of the refined biooil was 82.7 % C, 15.3 % H, 0.2 % N and 1.8 % O, no S. Its viscosity was 0.006 Pa.s and a heat of combustion of 43 MJ kg⁻¹. The refined biooil fraction contains n-alkanes, ranging from n-C₁₄ to n-C₂₇, alkenes varying from C₁₀:₁ to C₂₂:₁, and long-chain alcohols. The refined biooil makes a good diesel fuel due to its chemical and physical properties.
