Definitions
- the present invention relates to a composition of aviation gasoline (Avgas) lead-free, intended for aircraft with piston or reciprocating engines.
- the present invention relates to a high-octane aviation gasoline lead and having very good combustion characteristics.
- Aviation gasoline is a carefully crafted product subject to stringent regulations that go hand in hand with any aeronautical application.
- the refinery preparation, aviation gasolines is carried out with bases characterized by both a narrow distillation range and high octane numbers.
- bases are generally constituted by alkylates, reformates and isopentane cuts, the latter being used in low concentration because of their high volatility.
- aviation gasolines Before being placed on the market, aviation gasolines must meet other specific physico-chemical characteristics defined by international specifications. Thus, aviation gas must have a low vapor pressure to avoid vapor lock problems at low pressures encountered at altitude and for obvious safety reasons. The final distillation point must be low enough to limit deposits formation and their adverse consequences (power losses, deteriorated cooling).
- PCI heating value
- the refiner In order to guarantee the high octane requirements, the refiner generally proceeds, at the stage of manufacture of aviation gasoline, with the addition of an organic lead compound, and more particularly tetraethyl lead (PTE). .
