Petrolino Hydrocarbon Blending It is a specialized product of light and heavy refinery compounds designed to regulate the physical and chemical properties of fuels, solvents, and industrial oils.
This material is actually an engineered blend of paraffinic, naphthenic, and aromatic hydrocarbon cuts that are adjusted in precise proportions, depending on the needs of each industry, to optimize properties such as density, octane number, flash point, and viscosity in the final fuel or oil.
Due to its high purity and precise control of properties, Petrolino’s hydrocarbon blending is used in the production of industrial fuels, lubricants, proprietary solvents, and export petrochemical products.
Composition and technical nature of hydrocarbon blending
Hydrocarbon Blending Component is a refinery blend made from a controlled blend of various cuts including naphtha (C5–C10), heavier cuts (C11–C20), and certain amounts of isoparaffins and naphthenes.
This combined formula creates the following properties:
| Feature | Technical explanation | Importance in performance |
| High chemical compatibility | Combining multiple cuts with different weld points | Optimal evaporation and combustion control |
| Adjustable density (0.75–0.90 g/cm³) | Can be controlled by changing the light/heavy ratio | Suitable for fuel and oil |
| Medium to high octane number (70–90) | Dependent on the percentage of branched hydrocarbons | Improved engine and fuel performance |
| High flash point (>60°C) | Reducing the risk of flammability in transportation | High safety |
| Oxidative stability | Anti-oxidation additives | Preventing sludge formation in blending |
| Low sulfur content (<0.5%) | Refined according to D5453 standard | Environmentally friendly |

FAQ
What is hydrocarbon blending and how is it different from light and heavy cuts?
Hydrocarbon blending is actually an engineered combination of light and heavy hydrocarbon cuts, designed in specific proportions to achieve specific properties (such as octane number, density, flash point). Light and heavy cuts have limited properties individually, but blending is the optimal combination of both.
Where can I buy industrial blending hydrocarbon?
Petrolino Company, as a direct producer of hydrocarbon blending in Iran, supplies this product to the refining, lubricant and petrochemical industries.
Buying directly from the manufacturer means competitive prices, consistent quality and technical support.
Does this product comply with environmental standards?
Yes. Petrolino has reduced sulfur content to below 0.5% using Hydrotreating technology, which complies with international Low Sulfur fuel standards.
What is the difference between light and heavy hydrocarbon blending?
Light grades have a lower density and evaporate more quickly, while heavy grades have a higher flash point and greater thermal stability. The choice of grade type depends on the type of use (light fuel, industrial oil or heating fuel).
How can I request a sample and technical analysis?
You can request a COA (Certificate of Analysis) or technical sample via Petrolino’s contact form or the number listed on the product page. Petrolino’s sales team will respond as soon as possible.
