Petroleum, also known as crude oil, is a complex mixture of hydrocarbons that are found in the Earth's crust. The main components of petroleum include:
1. Paraffins: These are straight-chain or branched hydrocarbons with the general formula CnH2n+2. Paraffins are the most common type of hydrocarbon found in petroleum and are known for their high energy content.
2. Naphthenes: These are cyclic hydrocarbons with the general formula CnH2n. Naphthenes are also commonly found in petroleum and are known for their high octane rating, making them ideal for use in gasoline.
3. Aromatics: These are hydrocarbons that contain one or more benzene rings. Aromatics are known for their strong odors and are often used as solvents or as additives in gasoline.
4. Resins and asphaltenes: These are high molecular weight hydrocarbons that are found in the heavier fractions of petroleum. Resins are soluble in organic solvents, while asphaltenes are insoluble and form a solid residue.
5. Sulfur compounds: Petroleum also contains sulfur compounds, which can range from simple hydrogen sulfide to complex organic sulfur compounds. Sulfur compounds are undesirable in petroleum products as they can contribute to air pollution and corrosion.
6. Nitrogen compounds: Petroleum may also contain nitrogen compounds, which can range from simple ammonia to complex organic nitrogen compounds. Like sulfur compounds, nitrogen compounds are undesirable in petroleum products as they can contribute to air pollution.
Overall, the composition of petroleum can vary depending on the source and refining process, but it is primarily made up of hydrocarbons with varying molecular weights and structures.

Main Composition of Petroleum (Petrol)
Petroleum, also known as crude oil, is a complex mixture of hundreds of hydrocarbons, along with trace amounts of sulfur, nitrogen, and oxygen compounds. The specific composition varies depending on the source of the crude oil, but the main components typically include:
1. Hydrocarbons
- Alkanes (Paraffins): Unbranched chains of carbon atoms with hydrogen atoms attached to each carbon. The most common alkanes in petroleum are methane, ethane, propane, and butane.
- Cycloalkanes (Naphthenes): Rings of carbon atoms with hydrogen atoms attached. Cyclopentane and cyclohexane are common naphthenes in petroleum.
- Aromatics: Rings of carbon atoms with alternating single and double bonds. Benzene, toluene, and xylene are examples of aromatic compounds found in petroleum.
2. Sulfur Compounds
- Hydrogen Sulfide (H2S): A toxic, colorless gas that can be corrosive to equipment.
- Organic Sulfur Compounds: These include compounds such as thiols, disulfides, and thiophenes.
3. Nitrogen Compounds
- Nitrogen Gas (N2): A non-toxic, colorless gas that can be present in petroleum reservoirs.
- Organic Nitrogen Compounds: These include compounds such as pyridine, quinoline, and indole.
4. Oxygen Compounds
- Carbon Dioxide (CO2): A greenhouse gas that can be present in petroleum reservoirs.
- Organic Oxygen Compounds: These include compounds such as phenols and carboxylic acids.
5. Trace Elements
- Metals: Vanadium, nickel, and iron are common metals found in trace amounts in petroleum.
- Metalloids: Arsenic and selenium are examples of metalloids that can be present in petroleum.
Typical Weight Percentage Composition:
- Alkanes: 50-70%
- Cycloalkanes: 20-40%
- Aromatics: 10-25%
- Sulfur Compounds: 0-5%
- Nitrogen Compounds: <1%
- Oxygen Compounds: <1%
