煤油是一种含C9~C16的烃类混合物,主要来源于天然石油、页岩油或高温焦油,通过直馏或催化裂化的方法,经切割馏分即可获得不同规格的煤油产品[1]。煤油用途广泛,除了作为喷灯和航空涡轮发动机等的燃料外,还可用作机械零部件的洗涤剂、橡胶和制药工业溶剂等。煤油价格便宜、毒性小、无污染、能量较高,符合航天运载火箭对推进剂的选用要求,将作为我国新一代大推力运载火箭的主体推进剂投入到航天发射中。 Kerosene is a mixture of hydrocarbons containing C9 ~ C16, mainly derived from natural oil, shale oil or high-temperature tar, through the straight-run or catalytic cracking method, cut the fraction to get different specifications of kerosene products [1]. Kerosene is used in a wide range of applications. In addition to being a fuel for torches and aviation turbine engines, kerosene can also be used as a detergent for machinery parts, rubber and pharmaceutical industry solvents. Low price of kerosene, low toxicity, no pollution, high energy, in line with the requirements of space rocket propellant selection, will be the main propellant of China’s new generation of high thrust launch vehicle into space launch.
