NOVELTY - Preparing household fuel of biologic alcohol oil comprises: mixing water with emulsifying agent in a container, stirring or air inflating, uniformly mixing until no suspended matter and precipitate are saw, adding carbinol in the container, adding stirred mixed solution of emulsifying agent and water, mixing and stirring and obtaining the biologic alcohol oil after stewing; mixing the obtained biologic alcohol oil with the mutual solvent e.g. potassium permanganate; and mixing the obtained mixture of biologic alcohol oil and the mutual solvent with smoke abatement and deodorant.    USE - The process is useful for preparing household fuel of biologic alcohol oil (claimed), which is useful as substitute for diesel oil, liquefied gas and coal gas in industry, commerce, restaurants, hotels, organs and units, enterprise and public institutions and schools.    ADVANTAGE - The process: uses pollution free materials; provides household fuel of biologic alcohol oil with high fuel value and good stability. The emulsifying agent used in the process is very little of only about 1%, hence controls preparation cost of biologic alcohol oil.    DETAILED DESCRIPTION - Preparing household fuel of biologic alcohol oil comprises: (a) mixing 7-14 wt.% of water with 0.8-1.5 wt.% of emulsifying agent in a container, stirring or air inflating for 20-30 minutes, uniformly mixing until no suspended matter and precipitate are saw, adding 85-92 wt.% of carbinol in the container, adding stirred mixed solution of emulsifying agent and water, mixing and stirring for 25-30 minutes and obtaining the biologic alcohol oil after stewing for 4.5-5.5 hours; (b) mixing the obtained biologic alcohol oil with the mutual solvent according to the following ratio: 95-99% of biologic alcohol oil, 1-5% of mutual solvent comprising potassium permanganate (45-65%) and 35-55% of isobutanol or normal butanol; (c) mixing the obtained 93-98% of mixture of biologic alcohol oil and the mutual solvent with 2-7% of smoke abatement and deodorant, where the antismoke agent (45-65%) is ferrocene and deodorant (35-55%) is camphene or ammonia water or ethyl acetate.
