PHYSICAL PROPERTIES OF GASOLINE/METHANOL MIXTURES

摘要

Experimental work was done to relate selected physical properties of gasoline/methanol solutions, containing contaminant levels of water, to compositional and physical properties of the blending gasoline.nWater tolerance, octane number, vapor pressure, and distillation data are presented for eight gasolines and for their methanol solutions at methanol levels up to 20 wt-pct. The water tolerances of these fuels were strongly dependent upon temperature, methanol concentration, and gasoline composition. To cover a wider range of compositional effects, water tolerance measurements were made at selected methanol levels on a variety of individual hydrocarbons, refinery stocks, and gasolines selected for specific compositional character¬istics.
