タイトルまたは説明

Aviation kerosene  is a complex mixture of relatively volatile hydrocarbons. The higher performance grades are produced by blending specially manufactured high octane petroleum fractions consisting of paraffins and light aromatic compounds. Aviation gasoline grades are identified in specifications by their minimum anti-knock engine ratings. The use of incorrect grade can have disastrous results in terms of engine performance and aircraft safety. In order to differentiate between grades, dyes are added to the fuels in accordance with an internationally agreed colour code to impart a distinctive colour.
Aviation  fuels (jet fuels) are manufactured predominantly from straight run kerosene which normally require further treatment to meet the specification requirements. At some refineries there is an increasing tendency to incorporate proportions of product produced by hydrocracking processes.
The Check List for Jet A*1, a kerosine fuel having a maximum freezing point of **7oC, forms the basis of international supply of virtually all commercial aviation world-wide. Most military organisations now use kerosine type fuels which are virtually indentical to Jet A*1 in basic properties, differing mainly in the types of additives required. In areas where the same basic grade is used by both military and commercial industries, only one grade need be manufactured, stored and distributed as the additives required by the military can be injected as the fuel is supplied to the military.
