Introduction
Analysis of the core content of the standard
Comparison of key technical indicators
| Test items | Requirements for traditional aviation fuel | Additional requirements for synthetic hydrocarbons | Test methods |
|---|---|---|---|
| Aromatic content | ≤25% | ≥8% | GB/T 11132 |
| Distillation temperature difference | - | T50-T10≥15℃ T90-T10≥40℃ | ASTM D 2887 |
| Sulfur content | ≤0.3% | ≤15mg/kg(synthetic component) | ASTM D 5453 |
Synthesis Process Characteristics Analysis
Fischer-Tropsch Synthesis (FT-SPK)
- Feedstock: natural gas/coal-based synthesis gas
- Characteristics: Cycloalkanes ≤15%, almost no aromatics
- Density range: 730-770kg/m³
Fatty Acid Hydrogenation (HEFA-SPK)
- Feedstock: animal and vegetable oils and fats
- Key Control: FAME content ≤5mg/kg
- Metal impurities: single item ≤0.1mg/kg
Key points for implementation
- Batch management: Synthetic components are only applicable to initial production batches
- Additive specifications: Antioxidants need to be added immediately after fractionation (17-24mg/L)
- Thermal stability verification: Tube wall rating <3 after 2.5 hours of testing at 325℃
Background of standard evolution
This standard is based on the framework of GB 6537/DEF-STAN 91-91, and adds the following for the characteristics of synthetic hydrocarbon fuels:
- Specify the manufacturing process requirements for synthetic components
- Establish a distillation temperature difference compensation mechanism
- Strengthen trace element control (N≤2mg/kg)
