Plankton and algae thrived in ancient oceans, and when they died, their bodies sank to the seafloor. Unsaturated Hydrocarbons: The Olefins and Aromatics Crude oil also contains unsaturated hydrocarbons, which are less stable but highly valuable for manufacturing.
Molecular Families and Size: Understanding Crude Oil's Composition
To understand what oil is made of, one must look back millions of years to the ancient seas and forests where organic matter accumulated and transformed. Sulfur is a common contaminant; its presence defines the "sour" or "sweet" classification of oil and requires removal to prevent acid rain during combustion.
Depending on the specific conditions—depth, temperature, and the original biological material—this process yielded different types of hydrocarbons, ranging from light gases to heavy tars. This geological cooking process, known as diagenesis and catagenesis, broke down the complex organic molecules.
Exploring Crude Oil Families and Molecular Size Distribution
Paraffins are typically the primary component of gasoline and diesel fuel. Aromatics, including benzene, toluene, and xylene, have ring-shaped structures that provide high energy density and are critical for producing synthetic fibers, resins, and industrial solvents.
