一吨煤若用来发电,可生产1660～2500度电。 一吨好的炼焦煤,经高温焦化可得到700～800公斤焦炭、30～40公斤煤焦油、300～400立方米煤气、10公斤粗苯和10公斤硫酸铵。 一吨煤可炼油2吨。 一吨煤可生产化肥2吨。 一吨煤低温干馏所得液体和气体燃料的热能,基本上同直接烧一吨煤产生的热能相等。此外,可额外获得10多公斤合成橡胶、600米合成纤维布和50多公斤化肥。
If a ton of coal used to generate electricity, can produce 1660 ~ 2500 degrees of electricity. A ton of good coking coal, high temperature coking available 700 to 800 kg of coke, 30 to 40 kg of coal tar, 300 to 400 cubic meters of gas, 10 kg of benzene and 10 kg of crude ammonium sulfate. One ton of coal can be refined 2 tons. One ton of coal can produce 2 tons of fertilizer. The thermal energy of liquid and gaseous fuels derived from the pyrolysis of a ton of coal is basically the same as the heat energy produced by burning a ton of coal directly. In addition, an extra 10 kg of synthetic rubber, 600 m of synthetic fiber cloth and over 50 kg of fertilizer are available.
