Description

Bioalcohol oil prepared from waste oil product technical field

[00011] The present invention relates to a biofuel, in particular to a bio-alcohol oil for use in the preparation of a stove using waste waste oil as a raw material. Background technique

[0002] Waste oil is a mixed oil for the mixing of impurities, also known as hydrophobic oil, containing various chemical elements such as carbon, hydrogen, oxygen, pin, calcium, potassium, manganese, iron, m, etc. The main component is stearic acid. Glycerides and palmitate sleeves and a variety of edible residual mixtures. Ditch oil includes Ξ: Class: It is the oily floating material in the sewer or the oil that is simply processed and extracted from the leftovers and leftovers of the restaurant, the restaurant; the second is the inferior pork, pig viscera and pigskin processing. And the oil produced after the refining; the third is the waste oil used for the fried foods when the number of times of use of the oil exceeds the prescribed value, and the harmful substances such as peroxide value and acid value exceed the standard. Because the composition of the waste oil is complex and harmful to the human body, the legal and effective use of the waste oil is of great significance for reducing food safety and avoiding environmental pollution.

[0003] The existing cookware dips are mainly diesel, liquefied gas, pipeline gas and natural gas, and a few rural areas use biogas. Among them, the fire temperature of gas and liquefied gas is 400 900 °C, which can meet the needs of popular households and small and medium-sized catering, but it can not meet the requirements of high temperature 900-1200 °C for large and medium catering, and the safety hazard of carbon monoxide poisoning in liquefied gas and pipeline gas. Liquefied gas also has the danger of explosion, and its accidents often occur throughout the country; and the gas is not fully benefited by the urban and rural people due to the problems of pipeline equipment and facilities. Natural gas is limited by resources and cannot be spread across the country. Diesel has a high calorific value, but it produces a lot of soot after combustion, which seriously affects the environment. Bio-alcohol oil is a kind of environmentally-friendly biofuel that is newly developed from methanol. It can be stored, transported and used under normal temperature and pressure. It can be stored in ordinary metal or plastic containers. It has been tested by the national quality inspection department and has been promoted through experiments. Application, its technical performance and safety indicators meet the requirements of the state for civilian dips, is an ideal green fuel. If the bio-alcohol oil is prepared by using the mantle oil, not only can the gutter sleeve be legally and effectively reused, but the ditch oil is also a high-quality raw material for preparing bio-alcohol oil.

Summary of the invention

10004] In order to legally and effectively reuse the waste oil, the present invention proposes a technique for preparing a bio-alcohol oil having better combustion performance by using a waste oil product.

[0005] A bio-alcohol oil prepared from a waste oil product, characterized in that the bio-alcohol oil is produced by a waste oil by a ratio of 3⁄4 ί, that is, an emulsifier of 3 35 parts and a water of 25 parts to form an emulsion. After standing for 10 24 hours, it is mixed with 40 95 parts of methanol and allowed to stand for 4-8 hours. Among them, the trench: oil product is a kind of glyceryl stearate obtained by removing moisture and impurities from the waste oil. An emulsifier obtained by saponification of glyceryl palmitate.

[0006] The glyceryl stearate and glyceryl palmitate are obtained by the following methods: Take the right amount of waste oil, boil and filter, filter the liquid to be cooled, then use the split method to separate the oil, then add the oil to the capped container, carbonize at 400~700 °C, cool and filter. The filtrate is a mixture of glyceryl stearate and palmoate. In industrial production, methods of separation and purification can also be used instead of carbonization.

[00Θ7] The waste oil described above may first filter out larger solid impurities during the heating process, leaving less impurities and filtrate, and the filtrate also contains less impurities and moisture, so that it needs to be diverted. The oil is extracted and the water is discarded. At this time, the oil contains small impurities and cannot be separated. Therefore, it is necessary to further carbonize the precipitate, and the precipitate is removed by filtration, thereby ensuring the hard fat in the filtrate. The content of the mixture of acid oil ester and glyceryl palmitate reached 953⁄4.

[0008] The saponification process of the stearic acid 1 oleyl ester and palmitic acid oleate is:

70~90 parts by weight of the mixture of stearic acid oil ester and glyceryl palmitate, 6~16 parts of sodium hydroxide or sodium carbonate and 4~14 parts of water boiled for 30^60 minutes, slowly in the boiling process Stir.

[0009] After the saponification reaction, glyceryl stearate and glyceryl palmitate form sodium stearate, sodium palmitate and glycerol under the action of a strong alkali of sodium hydroxide or sodium carbonate, and the saponified product is yellow powder. grain.

[001 θ| The distiller oil emulsifier and water can be dissolved to form an emulsified solution, which is a polar substance and is a miscible mixed liquid.

[0011] The bio-alcohol oil of the present invention is composed of a waste oil product, methanol and water, wherein the waste oil product is not only an excellent emulsifier, but also a high calorific value material. The Chinese application number is CN201110274634.2. A new environmentally-friendly and energy-saving bio-alcohol oil patent is disclosed, in which at least 75% of methanol is required to reach the calcination calorific value of 8600 kcal; and the bio-alcohol oil of this patent requires only 40% of alcohol at least. , the amount of the alcohol is greatly saved, and the combustion value of the 35% waste oil product of the 3⁄4 can be as high as 9000 kcal, which is greater than the combustion value of the methanol, so the methanol fuel of the present invention is more than the patent disclosed in the patent. Methanol fuel is more efficient.

[0012] The bio-alcohol oil of the invention has stable performance, is not volatile, has a freezing point of -90 Ό, does not self-ignite, has a igniting temperature of more than 200 Γ, has no pressure, does not explode, and is accidentally ignited and ignited. The product is non-toxic, non-toxic, odor-free, and smokeless. It is a renewable new energy source for biomass. It has been monitored by relevant departments in accordance with national regulations.

[0013] The bio-alcohol oil combustion value can reach 5 00~9000 kcal/kg, so it is widely used, and can directly replace diesel, liquefied gas, pipeline gas, natural gas, and the family and snacks widely used in urban and rural areas. Shop, hot pot restaurant, hotel, unit canteen, steam boiler and small and medium industrial burning, soup, cooking, cooking.

[0014] The bio-alcohol oil adopts ffl gully product as raw material, which not only has good combustion performance, but also has low cost, and has important significance in reducing food safety threat, avoiding environmental pollution of waste oil and reducing fossil fuel consumption.
