NOVELTY - A synthetic fuel comprises (in parts weight) methanol (70-95), fuel (20-30) having high calorific value, combustion adjuvant (5-15), and emulsifier (0.3-0.7). Methanol is 95 vol.% refined methanol or 75 vol.% crude methanol. The fuel having high calorific value is a mixture of diesel oil or engine oil with castor oil and soybean oil. The combustion adjuvant is a mixture of acetone, hydrogen peroxide, potassium permanganate, dicyclopentadienyl iron, and water.    USE - Synthetic fuel is used for meal cookers, and small and middle boilers.    ADVANTAGE - The synthetic fuel is environmentally-friendly, efficient and economical (cost is decreased by 30%), and has high calorific value equivalent to diesel oil, and combustion efficiency.    DETAILED DESCRIPTION - A synthetic fuel comprises (in parts weight) methanol (70-95), fuel (20-30) having high calorific value, combustion adjuvant (5-15), and emulsifier (0.3-0.7). Methanol is 95 vol.% refined methanol or 75 vol.% crude methanol. The fuel having high calorific value is a mixture of diesel oil or engine oil with castor oil and soybean oil. The combustion adjuvant is a mixture of acetone, hydrogen peroxide, potassium permanganate, dicyclopentadienyl iron, and water. The emulsifier is a mixture of fatty alcohol-polyoxyethylene ether, alkyl phenol-polyoxyethylene ether, polyoxyethylene-sorbitan fatty acid ester, and polybasic acid amide, or a mixture of fatty alcohol-polyoxyethylene ether, alkyl phenol-polyoxyethylene ether, polyoxyethylene-sorbitan fatty acid ester, and sorbitan fatty acid ester, and nascent soap.    An INDEPENDENT CLAIM is included for preparation of synthetic fuel, which involves adding weighed soybean oil and castor oil in a container, heating to 60 degrees C, starting high-shear emulsion machine, stirring for 30 minutes at 1000 rpm, adding emulsifier, increasing stirring speed to 3000 rpm, stirring for 10 minutes, adding diesel oil or engine oil, decreasing the stirring speed to 1500 rpm, dispersing for 10 minutes to obtain a pre-emulsified oil, adding the pre-emulsified oil to methanol within 40-60 minutes at 1500 rpm, adding combustion adjuvant, and stirring for 5-8 minutes.
