Alcohol-based fuel produced by using frying waste oil and preparation method thereof

Abstract

The invention discloses alcohol-based fuel produced by using frying waste oil and a preparation method thereof. The preparation method comprises the following steps: adding n-hexanol, sec-octyl alcohol and oleic acid mixed liquid with the volume fraction of 8% to pretreated frying waste oil with the volume fraction of 12%, uniformly mixing, then adding ferrocene with the methanol mass fraction of 0.60% in the solution, vibrating by using an ultrasonic cleaner till the ferrocene is completely dissolved, finally adding methyl alcohol liquid with the volume fraction of 100%, and fully stirring till the liquid is uniform and transparent, thus obtaining the alcohol-based fuel. As a cosolvent and a combustion improver are added to the alcohol-based fuel, the alcohol-based fuel and polar low alcohol molecules are intermiscible, and the alcohol-based fuel and macromolecular fatty acid ester are also intermiscible; the cosolvent and the combustion improver have bridge effects, so that the alcohol-based fuel and the fatty acid ester are intermiscible very well. The ferrocene has a good combustion-supporting effect, so that dehydrogenation reaction and cleavage reaction are reduced in a combustion process, and the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the field of biomass energy, in particular to an alcohol-based fuel produced by frying waste oil and a preparation method thereof. Background technique [0002] Alcohol-based fuel is a liquid fuel based on methanol and ethanol. It is the cheapest and cleanest fuel next to hydrogen. It can be derived from biomass fermentation and fossil fuels such as coal, oil, and natural gas. Alcohol-based liquid fuel has the advantages of cleanliness, low price and easy storage, making it gradually become a common civil fuel, which can replace liquefied petroleum gas and be used in homes and restaurants. Frying waste oil is also called hogwash oil, which is obtained by heating food residues and taking the upper layer of fat. Sometimes animal and vegetable fats and various low-quality oils are collectively referred to as frying waste oil. my country has a large amount of frying waste oil with a wide range of sources. Making good use of th...

But if you don't manage it well and make good use of it, it will cause a lot of trouble

In recent years, some unscrupulous merchants have recycled waste frying oil at a low price, and returned the waste frying oil to the dining table through decolorization, deodorization, purification and other processes, which has greatly threatened the health of the people and disrupted the economic order of our country.
