Formula and manufacturing technology of alcohol-based fuel?

Alcohol-based fuel is a kind of fuel mainly composed of alcohols (such as methanol, ethanol and butanol).

Alcohol-based fuel oil is the latest scientific and technological achievement in China. It is an incidental flammable liquid produced by a chemical fertilizer plant that produces nitrogen and ammonia through a national compulsory methanol plant. We add calorific value enhancer, modifier, combustion improver, oxidant, stabilizer, smoke suppressant and flavoring agent in a certain proportion.

process flow

The biggest market for alcohol-based liquid fuels is commercial calorific value, not civil use. The biggest difficulty is not the formula, but the price of alcohol-based liquid fuel is too low and the volume is too large to save compared with diesel. Ordinary liquefied gas and diesel stoves have been transformed into alcohol-based stoves. Although many beginners have mastered the formula, they can't open the market at all. Faced with a large number of schools, factories and mines, they have no way to start, and they can gain huge profits by losing one pair of hands in vain. The biggest reason is that the amount of products provided to users is too large and the firepower is small, and users report pungent and tearful.

Alcohol-based fuels are mainly used in hotels, restaurants and other places where fires are concentrated. The technological process is mainly as follows: main raw material of bio-alcohol oil+(auxiliary material 1)+ (auxiliary material 2)→ biochemical synthesis → storage tank → finished product sales. The investment scale of bio-alcohol oil can be large or small, which should be determined according to its own investment ability and local market capacity.

: use

1. Alcohol-based fuel can be used in restaurants and industrial boilers.

2. Alcohol-based fuel has obvious economic comparability-compared with liquefied gas, diesel oil and kerosene, its greatest feature is high thermal efficiency. Since 2008, the advantages of alcohol-based fuels have attracted the attention of the industry. However, it is technically difficult, and more advanced technical research and practice are needed to synthesize fuels equivalent to gasoline and diesel. By the end of 20 12, domestic petrochemical oil products and alcohol-based environmental protection oil products can be fully tested and developed.

Alcohol-based fuel is a kind of green energy-compared with coal, coal tar, heavy oil, diesel oil and gasoline, alcohol-based fuel has the most complete combustion and the highest heat conversion efficiency, and its emissions are mainly water and carbon dioxide, so it is the cleanest, most environmentally friendly and most promising future fuel.

3. In developed countries, alcohol-based fuel has been used in fighter planes to replace aviation kerosene fuel.

Thermal energy alcohol-based fuel

Mainly used in industrial heat sources, central heating, hotel canteens, factory restaurants, family kitchens and so on. This technology includes alcohol-based fuel, petroleum fuel, environmental protection blending and so on. , covering all kinds of alcohol-based fuels in China. According to the types of customers and seasonal differences, we have developed different blending technologies for basic raw materials and formulated product standards for various products.

Environment-friendly fuel ensures the deployment scheme of alcohol-based fuel in different seasons, which can meet the needs of different regions and users. At present, the uses of alcohol-based fuels based on heat energy are mainly divided into three categories, which are used in civil, commercial and collective restaurants. The performance of the three types of products is basically the same, but the audience and customer groups are different, so different marketing schemes should be adopted for differentiated marketing.

Power alcohol-based fuel

It is mainly used in diesel vehicles, gasoline vehicles, engineering vehicles, generator sets, marine fuels and so on. This technology includes alcohol-based power fuel, national standard oil blending, environmental protection oil blending with diesel oil and so on. , covering all domestic power petroleum products and environmentally friendly fuels. According to the types and seasonal differences of customers and the requirements of power equipment, different basic raw material mixing technologies have been developed, and the product standards of various products have been formulated. The product details are as follows:

Methanol gasoline

Methanol gasoline can be used for all kinds of gasoline vehicles. Methanol gasoline has its inherent advantages, and its octane number is 1 12, which is higher than the national standard gasoline. After environmental protection blending, 100% methanol gasoline can be started normally at-35℃, and its low-temperature ignition performance can be solved. No gasoline, only a small amount of low-temperature ignition promoter. This technology is the first in China.

However, methanol gasoline has its inherent disadvantages. M 100 methanol gasoline is not suitable for long-term high-speed operation. If it runs over 3000 rpm for a long time, please add 10- 15% gasoline, otherwise it will lead to high temperature breakdown of the spark plug. At present, production bases with an annual output of 800,000 tons of methanol and gasoline have been built in Wuxi, Xuzhou and Chongqing.

Methanol diesel oil

Methanol has an innate cetane number of 3, so it does not have the basis to completely replace diesel; Moreover, the flash point of methanol is low, and the profit per ton of methanol and diesel oil after environmental protection blending is 800- 1000 yuan (increased on the basis of the original profit), which ensures that the flash point can be safely stored and can be used by all imported domestic cars.

superiority

The burning value of biofuel is lower than that of LPG and diesel, but its price is more advantageous. It can be used as an alternative fuel for liquefied petroleum gas and diesel oil. It has the characteristics of low price, safety and convenience, no residue, no black pot bottom, cleanliness and safety, low price, easy purchase of raw materials and convenient use, and is a clean biomass energy encouraged by the state. The cost is only about one-third of the wholesale price of liquefied petroleum gas or diesel oil, and the profit margin is huge, which has extremely high investment value.

This type of fuel oil is an updated product of alcohol-based liquid fuel, which solves the problems of low calorific value, low thermal efficiency, large consumption, environmental protection and uneconomical. It not only completely conforms to the national standard of alcohol-based liquid fuel, but also greatly improves and enhances its calorific value, viscosity and flame temperature.

Most restaurants in large and medium-sized cities in China, such as restaurants, hotels and university canteens, use diesel and liquefied gas as Chinese cooking stoves, and some still burn coal. Bio-alcohol oil is a newly developed eco-friendly bio-fuel based on alcohol-based fuel. It can be stored at normal temperature and pressure, without high-pressure steel cylinder, just in ordinary metal or plastic containers.

Under the background of increasingly exhausted fossil fuel resources, alcohol-based fuel, as a carrier of new clean energy and carbon cycle, not only solves the problem of efficient storage and distribution of energy, but also its diverse synthesis methods and the re-synthesis and recycling of carbon dioxide and other wastes are of great significance to alleviating global warming.
