Refined petroleum products are fuels and other materials derived from crude oil through a process called refining. This process involves separating and transforming the various components of crude oil to create usable products like gasoline, diesel, and jet fuel. These products are essential for transportation, heating, and electricity generation. In addition to fuels, refined petroleum products include lubricants, asphalt, and petrochemicals, which are used to make plastics and other synthetic materials. The refining process is crucial for meeting energy demands and supporting various industries, making refined petroleum products vital to modern economies and daily life.
