Dried ground seven biomass samples were converted to charcoal, liquid, and gaseous products using pyrolysis at different temperatures. From 27.7 to 44.0% liquid pyrolysis products were obtained from pyrolysis of the biomass samples With a heating rate of 2.2s/K at a 293-870 K temperature range. The acetone solubles of the pyrolysis products were added to gasoline. Solubilities of the acetone solubles in gasoline were tested as 3.4-6.8% by weight. When 10% methanol is added to gasoline, the octane number-increased by 14%. The C-3, C-4, and C-5 iso- and n-alcohols were found to be the most effective blending agents in reducing phase-separation temperature. Iso-amyl alcohol was found to be the most effective blending agent for methanol-gasoline blending engine fuels.
