Oxygen Compounds: Including resins and acids, these oxygen-containing molecules contribute to the acidity of some crude oils. This processing reveals the practical significance of understanding the oil's molecular composition, as different feedstocks require specific refining approaches to maximize yield and quality of products like gasoline, jet fuel, lubricants, and petrochemical feedstocks.
What Hydrocarbons Make Up Crude Oil: Key Components and Breakdown
Unsaturated Compounds Beyond the structural classification, hydrocarbons in crude oil are also distinguished by their saturation levels. API gravity measures the density of the oil relative to water, with lighter oils being more valuable due to higher yields of gasoline and diesel.
These non-hydrocarbon components include: Sulfur Compounds: Present in varying amounts, sulfur is a key impurity that affects refining processes and emissions. Crude oil is a complex mixture of hydrocarbons, organic compounds, and trace elements formed from the remains of ancient marine organisms.
What Hydrocarbons Make Up Crude Oil: Composition and Types
Distillation separates components based on boiling points, while cracking breaks down heavy hydrocarbons into lighter, more valuable fractions. Aromatics: Ring-structured hydrocarbons that are often associated with higher octane ratings but can be environmentally problematic.
