    Oil shale is an ore with very low oil content, and the development and utilization cost is very high. When **** rose from more than $30 per barrel to more than $100 per barrel, the market began to look at oil shale. But when the **** fell to more than 60 US dollars barrel, many people, in the situation of the international financial crisis, the demand for oil will decrease, and the oil ** may decline further, and the economics of investment in oil shale projects are debatable.

    The market comprehensive oil price is 10-15 US dollars per barrel, when the international **** is 10 15 US dollars per barrel, the production of shale oil breakeven (range), and now the international **** is above 75 US dollars per barrel (OPEC), and the profit margin can be seen. Oil shale refining is the direction encouraged by national policies, but the new technology of oil shale refining is immature, and the technical threshold is relatively high. The old technology is mature, but the yield is low. The major shareholder of Kyrgyzstan Electric Co., Ltd. gave up the oil shale investment project; Liaoning Chengda announced a capital increase of 100 million yuan for a comprehensive oil shale development project.

    The investment outlook is mixed. The vast majority of the world's oil shale oil is produced by dry distillation of the ground. Whether it's open-pit or underground mining, the oil shale is eventually collected to the surface and then processed using dry distillation technology to produce shale oil, tailings and slag.

    The shale oil obtained from dry distillation can be used as fuel oil or refined, and the tailings and slag can be used as other raw materials, or disposed of after environmentally friendly treatment. The limitations of the surface dry distillation method are relatively large, one is the low recovery rate of underground oil shale, the second is the serious damage to ecology and water quality, the third is the serious pollution of ash and slag, and the fourth is that direct mining occupies a large area and cannot be completely repaired after reclamation. Fifth, it will lead to self-serious geological disasters.

    The shortage of oil resources restricts the development of the economy, and the development of oil shale replaces the natural resources and supplements the shortage of oil resources, which is the main topic of energy development research in various countries. As international oil prices continue to rise, the demand for shale oil will also increase. Some foreign countries with oil shale resources, such as Estonia, the United States, Germany, Israel and Australia, etc., attach great importance to the development of oil shale resources, are carrying out research work on oil shale development, and even have mastered advanced technology, formulated development plans and plans, when the natural resources are depleted or scarce, shale oil will meet the needs of some oil consumption markets.

    As an alternative energy source for oil, oil shale has attracted worldwide attention, and the oil shale market will be a group of champions, which is a "blue ocean" to be developed. The scale of Fengtai oil shale in Huadian City, Jilin Province is small, and it is still at a disadvantage in the domestic oil shale competition market, but it will be good in the future.

    What is light oil.

    Mixtures of hydrocarbons with boiling points in the range of about 50 350 are not very strict. In the petroleum refining industry, it can refer to light distillate oil or light oil products. The former includes gasoline, kerosene, light diesel and other fractions, as well as head oil, residual oil, etc., which mainly come from distillation, catalytic cracking, thermal cracking, petroleum coking, hydrocracking and catalytic reforming; The latter is the oil obtained by the refining process of a light distillate.

    In the petrochemical industry, light oil is often called light oil, mainly including naphtha and atmospheric gas oil, which are mainly distilled and are important raw materials for tubular furnace cracking to produce ethylene. In coal chemical industry, light fractions with a boiling point lower than 210 in coal tar and direct coal liquefaction products are often referred to as light oil or light oil.

    The density of kerosene is. Kerosene mainly refers to a chemical substance and is a class of light petroleum products. Kerosene, also known as fire oil and fire water, is a mixture of hydrocarbons obtained by fractionation of bucket oil.

    It is a colorless and transparent liquid, and it is light yellow when it contains impurities. Slightly foul-smelling. Insoluble in water, soluble in alcohols and other organic solvents.

    Volatile. Flammability.

    After the kerosene is volatilized, it is mixed with air to form the most advanced mixture. The combustion is complete, the brightness is sufficient, the flame is stable, no black smoke, no lights, no obvious peculiar smell, and little pollution to the environment.

    Kerosene is miscible with petroleum solvents. The solubility to water is very small, and kerosene containing aromatic hydrocarbons has greater solubility to water than kerosene, an aliphatic hydrocarbon. Kerosene dissolves absolute ethanol. Mixtures with alcohols stratify when water is present at low temperatures.

    Kerosene has different chemical compositions for different purposes. The physical and chemical properties of the same kerosene are also different due to different production methods and origins. It is mainly used for lighting and fuel for various blowtorches, gas lamps, vaporizers and kerosene stoves; It can also be used as a detergent for mechanical parts, a solvent for rubber and pharmaceutical industries, an ink thinner, a pyrolysis raw material for organic chemicals, and so on.

    It is mainly used for lighting and fuel for various blowtorches, gas lamps, vaporizers and kerosene stoves; It can also be used as a detergent for mechanical parts, a solvent for rubber and pharmaceutical industries, an ink thinner, and a pyrolysis raw material for organic chemicals; Process oils for glass ceramics industry, aluminum plate rolling, chemical heat treatment of metal workpiece surfaces, etc.; Some kerosene is also used to make thermometers. According to the application, it can be divided into thermal kerosene, lighting kerosene, etc.

    Kerosene is used as fuel for kerosene lamps and as a detergent. In a kerosene lamp it burns steadily, but emits greasy black smoke. Use as a cleaner.

    Kerosene agent It can remove very strong greasy and dirt attached to the metal surface. Some model aircraft use kerosene as fuel or use fuel adulterated with kerosene.

    In the past, 25% kerosene was added to diesel to reduce the viscosity of diesel when it was cold. This method is no longer used today. Modern diesel engines cannot use diesel mixed with kerosene.

    Kerosene, which is used as a detergent**, is very pure and does not contain heavy molecules, so it should not leave marks after wiping.

    Kerosene is less dangerous than gasoline. Aviation kerosene is kerosene mixed with other substances, it is the fuel for turbine engines, and it is also the fuel for rocket engines.

    Light it up! I remember when I was a child, if there was a power outage, I would light kerosene lamps. It's just a use that you don't have in general.

    There are a few other uses for kerosene.

    There are also some special ones that don't, and they have special uses.

    Dear, we are inquiring about the relevant information for you, please wait a while!

    The ignition point of kerosene is 80 84, and under normal circumstances, ordinary kerosene cannot be ignited directly. Whether it is a kerosene lamp, a kerosene stove or a kerosene firer, there needs to be a burning cotton thread to ignite under the action of the accelerant. The two necessary conditions for combustion must be oxygen and hit the ignition point, which should be ignited by a flame over a large area without insufficient temperature so it will not burn.

    And if kerosene is on paper, kerosene rarely reaches the ignition point easily, which is why kerosene ignites easily. However, if the amount of kerosene is relatively large and does not reach the ignition point, then kerosene is not particularly easy to ignite directly, although it is a flammable liquid. Especially for aviation kerosene, if the ignition point of kerosene reaches four or five, it is simply impossible to make it appear the possibility of combustion.

    Therefore, when you usually use kerosene, as long as you pay more attention, there will be no fire.

    Fire water and kerosene can not be distinguished, kerosene is commonly known as fire water, fire water is a general term for gasoline or kerosene, the main components are C 4 C 12 hydrocarbons, alkanes and other hydrocarbons. It is one of the mixed hydrocarbon articles. It is a colorless or yellowish, volatile and flammable liquid with a special odor.

    Dear, what are your specific questions?

    Yes, the current technology can do it.

    Coal chemical industry can produce methanol, and most of them are by-products, ** relatively cheap, methanol and gasoline can be mixed into methanol gasoline under the action of certain additives, becoming a substitute for gasoline, and now there are many cities in China that have put it into trial, such as Shanxi Province.

    Now the latest technology can do methanol without adding gasoline, through the role of some additives can directly replace gasoline, become a good gasoline substitute, reduce the cost and can greatly strengthen environmental protection.

    Now methanol gasoline is also used as fuel oil.
