Gasoline can be divided into three categories: Avgas, automotive gasoline, and solvent gasoline.
Mainly used as fuel for gasoline engines, widely used in automobiles, motorcycles, speedboats, helicopters, agricultural and forestry aircraft, etc.
Solvent gasoline is used in industries such as rubber, paint, grease, and spices. Straight run gasoline, thermal cracking gasoline, catalytic cracking gasoline, reforming gasoline, coking gasoline, superimposed gasoline, hydrocracking gasoline, Pyrolysis gasoline, alkylation gasoline, synthetic gasoline, etc.
Routine test items of gasoline: kinematic viscosity (100 ℃), viscosity index, flash point (opening), pour point, moisture, sulfate ash, mechanical impurities, foam property, low temperature dynamic viscosity, phosphorus, base number, sulfur.
Testing items and standards for gasoline used in vehicles:
1. Antiknock property: research Octane rating (RON) antiknock index (RON+MON)/2
2. Lead content Determination of lead content in gasoline (Atomic absorption spectroscopy) GB/T 8020-1987 (2004)
3. Distillation range
4. Determination of Vapor Pressure/kPa for Petroleum Products (Red Method) GB/T 8017-2012 Determination of Vapor Pressure for Petroleum Products Micro Method SH/T 0794-2007
5. Determination of Gum Content/(mg/100 mL) Fuel Gum Content by Jet Evaporation Method GB/T 8019-2008 ASTM D381-12
