Supply of kerosene (kerosene) priced at direct

Alias ??aviation kerosene. By straight-run distillate hydrocracking and hydrotreating component, etc., and the necessary additives blended in a transparent liquid. Component mainly composed of hydrocarbons of different composition of the fractions. Common kerosene is composed of many different chemical composition and properties of hydrocarbons are mixed together. General kerosene and aviation kerosene formula is CH3 (CH2) nCH3 (n is 8 to 16), but more pure aviation kerosene, impurities minimal. Judgment and general aviation kerosene kerosene ingredients not from the point of view, but from a number of indicators such as its calorific value, density and low temperature performance, in addition, its boiling ranges and viscosity also have certain requirements. China's production of aviation kerosene net calorific value of not less than 10250 kcal per kilogram, a density of not less than 0.775 g / cc. Jets flying at a height of meters above, when the high-altitude temperatures as low as -55C ~ -60C, which requires aviation kerosene can not be solidified at such low temperatures. The specific requirements of aviation kerosene index not higher than the freezing point of -55C ~ -60C, in order to ensure that the aircraft normally fly at high altitude. Aviation kerosene boiling ranges will affect the performance of the engine start and whether complete combustion, while the density of kerosene distillation range of circumstances and its own low temperature performance are directly related. The viscosity of aviation kerosene size affects the quality of work conditions and combustion engine fuel injectors. The viscosity is too large, large droplets sprayed into the engine, causing incomplete combustion, reduces engine output; viscosity is too small, so that mist spray angle is large, close range, can cause internal overheating. Because of the stringent requirements of aviation kerosene, aviation kerosene through the use of a partial conversion process, using cogel catalysts in the process, the amount of catalyst loading, less zeolite content, aromatics saturation and strong ability to obtain oil having a density density high smoke point, high calorific value, low aromatic characteristics. Kerosene combustion products are CO2 and H2O, but elemental H and C can be oxidized and burnt, so plenty of oxygen is a necessary condition for full combustion.
