Embodiment 4、5

[0033] Embodiment 4,5 is that the raw material from the refinery is pretreated and used for blending components of aviation gasoline. The corresponding components and their contents are shown in Table 3, and each component is blended to form Examples 4 and 5 respectively. aviation gasoline; its corresponding properties are shown in Table 4. It can be seen from Table 4 that the distillation range of the blended aviation gasoline meets the requirements of GB1787-2008, and the measured motor octane number, saturated vapor pressure, freezing point and water reaction volume change also meet the requirements of GB1787-2008.

Abstract

The invention discloses lead-free high-quality clean aviation gasoline which comprises the following components by volume percent: 40%-65% of alkylation gasoline, 6%-35% of debenzolized and reformulated gasoline, 3%-19% of methylbenzene, 5%-15% of isopropyl benzene, 3%-15% of industrial isopentane and 0-15% of MTBE; when industrial isooctane is selected as the alkylation gasoline and a mixture of methylbenzene and xylene is used as the debenzolized and reformulated gasoline, the aviation gasoline comprises the following components by volume percent: 45%-60% of industrial isooctane, 15%-30% of methylbenzene and xylene, 6%-15% of isopentane, 4-15% of industrial isopentane, 0-10% of MTBE and 0-6% of iso-butane. The blend aviation gasoline which is prepared by refining the raw materials and optimizing the components of the raw materials can meet the requirements of No.95 gasoline specified in GB1787-2008 under the condition of not adding lead.

Description

technical field [0001] The invention relates to aviation gasoline, in particular to a lead-free, high-quality clean aviation gasoline. Background technique [0002] Aviation gasoline is mainly used in piston aircraft engines, such as helicopters, communication machines, weather machines, trainers, etc. Military aircraft mainly use No. 75 and No. 95 aviation gasoline. At present, there are only two domestic enterprises producing aviation gasoline, namely Lanzhou Petrochemical Company and Qilu Petrochemical Company refinery. Lanzhou Petrochemical Branch produces three grades of aviation gasoline, No. 75, No. 95 and No. 100. The production process of No. 95 aviation gasoline mainly includes: refined oil blending process (80% aviation base gasoline, 10% industrial isooctane, 10% industrial cumene) and new formula refined oil blending process (53-54 industrial isooctane %, produced oil 28-29%, cumene 7-8%, C5 component 10-11%, tetraethyl lead 2.9-3.2g / kg). The blending process...
