Abstract
Abstract This invention relates to a fuel composition and process for making a fuel with high octane value for use in a spark ignition type internal combustion engine. More particularly, this invention relates to a process for preparing a substitute fuel composition comprising mixing 70.6% of a mixture of 65.0% methanol, 0.6% methanol+stearic acid (40:1) and 5.0% benzene, 20.4% of a mixture of 20.0% water, 0.3% dextrin and 0.1% phenol, 5% of combustion-accelerant consisted of 0.70% stearic methyl dichloride, 0.35% ethylene dichloride, 0.85% xylene, 0.02% lead acetate, 2.50% acetone and 0.57% aluminum stearate+acetone (1:40) as surfactant and 4.0% oxalic acid (1 Kg)+dimethyl ether (201) as antiknock agent; stirring said mixtures at 150-200 rpm for 2-3 minutes at 10°-40° C. and preserving them for 48-72 hours at room temperature.
