China has the advantage of coal to oil, but will not become the main direction of oil production experts believe that in China to engage in coal oil has a significant advantage. The rich coal less oil in recent years, with the development of economy, crude oil imports increased year by year, from 1993 to 2003 10 years, an average annual increase of more than 15%, import dependence is more and more high. 10 years, China's crude oil imports increased by 9.18 times a year to spend a lot of foreign exchange. Due to rising oil prices, in 2004 more than 55 billion yuan of imported crude oil last year. Therefore, experts believe that, from the strategic point of view of China's energy security, but also should strive to find ways to solve the problem of long-term supply of energy from the diversification, and coal oil is one of the feasible ways.
According to expert estimates, when the price of crude oil in more than 28 U.S. dollars, coal oil in the economy is more cost-effective; below this price, coal oil is not worthwhile. Therefore, in the middle of the 80s to the middle of the 90s, international oil prices have been at a low level, coal oil will naturally not be taken seriously. However, the technology has been quite mature, can be said to have a ready pen, as long as the needs of the market, can undertake large-scale industrialization. Until the last two years, international oil prices continue to rise, coal oil re put on the agenda by countries. The United States began to engage in indirect liquefaction last year, France, Italy began to cooperate in R & D. But from the start of the project to start the construction of at least 5 years of preparation time, and oil price changes frequently, while low, people tend to make decisions about the response lag.
Developed countries do not engage in the history of coal to oilIt is understood that South Africa has an annual output of 8 million tons of oil coal oil plant, is the world's only large-scale coal oil business plant, and provides the country with a transport oil of 60%. In fact, the United States, Germany, Japan and other developed countries have mature technology, but why they did not put into industrial production?According to reports, as early as the late 30s of last century, due to the shortage of oil, Germany began to study coal oil technology. Before World War II, Germany has built 17 factories, producing about 4200000 tons of gasoline and diesel. By the end of 40s and early 50s, with the exploitation of oil fields in the Middle East, a large number of low-cost oil flooded the market, 2 to $10 a barrel. In this case, then make coal into oil in the economy is very uneconomical. Until 1973, the Middle East oil embargo, oil prices pushed higher, $more than and 30 (equivalent to the current price of $more than and 80), then the coal oil development scale and climax, the United States and Japan and Germany have invested heavily in research, and construction of a pilot plant. However, in these countries, coal oil has not really put into commercial operation. Why is this?
