Gasoline
Gasoline 87 is a specific grade of gasoline derived from crude oil, categorized by its octane rating of 87, which is considered regular-grade fuel. Within the spectrum of petroleum derivatives, it falls under the category of light distillates, which are products obtained during the initial refining stages of crude oil.
Gasoline 87 in Petroleum Derivatives:
1. Position in Refining Process:
• Gasoline 87 is obtained through a combination of fractional distillation, cracking, and blending processes.
• Its low boiling point (30°C to 200°C) places it among the lighter fractions of crude oil, alongside other products like naphtha and kerosene.
2. Octane Rating:
• The octane rating of 87 indicates its ability to resist knocking or premature ignition in spark-ignition engines.
• It is typically used in engines designed for regular fuel, making it one of the most commonly produced and consumed gasoline grades.
3. Comparison to Other Gasoline Grades:
• Lower octane fuels like gasoline 87 are less resistant to knocking compared to higher-octane grades like 89 or 91.
• Gasoline 87 is more affordable but might not be suitable for high-compression engines requiring premium fuels.
4. Production:
• Produced through catalytic cracking and blended with additives to meet specific regulatory standards for emissions and engine performance.
5. Applications:
• Primarily used in passenger vehicles, small engines, and machinery designed for regular-grade gasoline.
