Heavy hydrocarbons refer to chemical compounds that are composed of hydrogen and carbon atoms and have a larger molecular weight. These compounds are known as heavy hydrocarbons due to their long carbon chains or more complex structural rings. Some of the features and uses of heavy hydrocarbons are: 1. **Heavy crude oil:** - Some oil sources contain heavy crude oil, which has a high concentration of heavy hydrocarbons. These oils usually have high specific gravity and different physical and chemical properties than light oils. 2. **Asphalt:** - This material is known as one of the heavy hydrocarbons and is used in the production of building materials such as asphalt for road construction, construction, and flooring. 3. **Diesel and heavy oil:** - Heavy hydrocarbons are used as main materials in the production of diesel and heavy oil. These fuels are used for diesel engines and power plants. 4. **heating consumption:** Some heavy hydrocarbons are used as fuel sources for domestic and industrial heating systems. 5. **Petrochemical:** - In the petrochemical industry, heavy hydrocarbons are used as raw materials for the production of various chemical products and plastics. Due to their characteristics such as high density and physical strength, heavy hydrocarbon compounds are used in various industries to produce energy, building materials, and a wide range of chemical products. 6. **Consumers of oil and gas:** - Some heavy hydrocarbons are used as raw materials in the production of oil and gas. These petroleum gases are used in the gasification industry to produce gases that can be used industrially and energetically. 7. **Biological consumables:** - In some cases, heavy hydrocarbons are used to produce biological materials, for example, heavy hydrocarbons are used in the production of biosulfur. 8. **Refineries and refineries:** - In the oil refining process and refineries, heavy hydrocarbons are separated from crude oil and used to produce different fuels and petrochemical products. 9. **Fuel for ships and transport fleet:** Some heavy hydrocarbons are used as fuel for ships and marine transport fleets. 10. **Use in metallurgical industries:** - Some heavy hydrocarbons are used as main materials in metallurgical processes to extract and refine metals. In general, heavy hydrocarbons are widely used in various industries due to their unique physical and chemical properties and play an important role in providing energy and producing raw materials. 11. **Production of heat and steam:** - Heavy hydrocarbons are used as thermal fuels in industrial heating systems and steam production for industrial processes. 12. **Electricity production:** - In thermal power plants, heavy hydrocarbons are used as fuel to generate electricity. 13. **Transport industry:** Some heavy hydrocarbons are used to produce fuels used in vehicles, including cars and motorcycles. 14. **Production of chemicals:** - Heavy hydrocarbons are used as raw materials in petrochemical industries to produce chemical products such as plastics, paints, resins, and other chemicals. 15. **Hot water production and housing heating:** - In home heating and hot water production systems, heavy hydrocarbons are used as fuel. Due to the wide range of features and applications of heavy hydrocarbons, these compounds play an important role in the global economy and are widely used in various industries.
