煤制油技术档（Coal oil technology file） Chinas total energy features are rich coal, less oil and gas. In 2003, Chinas total energy consumption amounted to 11.783 tons of oil equivalent, of which coal accounted for 67.86%, oil accounted for 23.35%, natural gas accounted for 2.5%, hydropower accounted for 5.43%, nuclear energy accounted for 0.83%. China has abundant coal resources, 2000~2003 years of proven reserves are 1145 tons, the reserve production ratio to drop in 2002 2000~2001 years 116 years 82 years 69 years, 2003. In 2003 32 tons of proven oil reserves and reserve production ratio of 19.1 years. In a long period of time, Chinas crude oil production can only maintain at 1.6~1.7 million tons / year level. Because of its large reserves and relatively stable price, coal has become the preferred fuel for Chinas power production. In the first 50 years of this century, coal will remain dominant in Chinas primary energy mix. It is estimated that the proportion of coal to primary energy will be 67.8% in 1999, 63.8% in 2000 and 67.8% in 2003, reaching about 50% in 2005. Our country burns about 30 million tons of heavy oil every year, the shortage of petroleum resources still make coal instead of oil on the agenda again. Coal making oil has become an important trend of energy strategy in our country. Indirect coal liquefaction technology It is called indirect coal liquefaction technology, which is produced by gasification of coal to produce synthetic gas and re - fund to produce synthetic oil. Indirect coal liquefaction has been industrialized in South Africa as early as possible. South Africa is a country of coal and oil, the coal reserves of up to 553.33 tons, reserve production ratio of 247 years. The proportion of coal to primary energy is 75.6%. Since 1955, South Africa has adopted coal gasification technology and Fischer Tropsch synthesis technology to produce gasoline, kerosene, diesel oil, synthetic wax, ammonia, ethylene, propylene, alpha olefins and other petroleum
