Here's a breakdown:
* Crude oil: A complex mixture of hydrocarbons (compounds containing only hydrogen and carbon).
* Fractional distillation: The process used to separate crude oil into different petroleum fractions. This works by heating the oil and separating the components based on their boiling points.
* Petroleum fractions: The individual groups of hydrocarbons that are separated during fractional distillation.
Examples of petroleum fractions include:
* Petroleum gas: The lightest fraction, used as fuel for cooking and heating.
* Gasoline: Used as fuel for cars and other vehicles.
* Kerosene: Used as fuel for jet engines and lamps.
* Diesel fuel: Used as fuel for trucks, buses, and trains.
* Fuel oil: Used for heating homes and businesses.
* Lubricating oil: Used to reduce friction in machinery.
* Wax: Used in candles, cosmetics, and other products.
* Asphalt: Used to pave roads and parking lots.
Important note: While these fractions are extracted from crude oil without being chemically changed, they may be further processed to improve their properties or to create specific products. For example, gasoline is often treated with additives to improve its performance.
