Why Was Synthetic Oil Developed?

Oil has been the backbone of global energy needs for over a century. However, as the demand for refined hydrocarbons continues to rise, the inherent challenges of refining natural crude oil pose significant limitations. This is where synthetic oil comes into play, offering a cleaner, more controlled alternative to the traditional methods of producing motor oil.

Introduction to Natural Petroleum

Naturally occurring petroleum is found in over a thousand different types, each requiring specialized processing methods. The most sought-after fractions, such as gasoline and diesel oil, are often lacking in heavier crude oils. Furthermore, natural petroleum contains impurities like asphaltenes, mineral matter, salt water, gaseous hydrocarbons, and sulfurous gases, which are largely waste products needing conversion or disposal. These processes can be quite expensive and environmentally taxing.

Advantages of Synthetic Oil

The development of synthetic oil aimed to address these shortcomings by providing an organic source of hydrocarbons that can be refined without the complexities and costs involved in petroleum processing. Germany's experience in the 1930s with coal-based gasoline production laid the groundwork for further exploration into alternative methods of producing desired fractions, such as gasoline, diesel oil, and motor oil.

Purity and Predictability in Synthetic Oil Production

Unlike natural oil, which is a blend of hydrocarbons ranging from methane to heavy tar, synthetic oil is a precisely controlled product. Synthetic oil is designed to have hydrocarbons within a specific molecular weight range, typically between 15-35 carbons, making it far more consistent and predictable. This is in contrast to natural oil, where refining processes still result in some smaller and larger molecules along with sulfur impurities. The consistent size and geometry of synthetic oil ensure that it performs reliably under a wide range of temperatures and engine conditions.

Addressing Sulfur Impurities
The sulfur in natural oil is a major issue, as it forms sulfuric acid and can damage engine components when water is present. In synthetic oil, there is no sulfur, thus eliminating the risk of engine corrosion and extending the lifespan of the engine components. This is a significant benefit, especially for high-performance and luxury vehicles.

Controlled Refinement Process

One of the key advantages of synthetic oil is the ability to control the molecular structure at every stage of the refining process. With synthetic oil, you can tailor the product to meet specific requirements, such as having an exact number of branched chains and unsaturated bonds. This precise control ensures that the oil has optimal flow properties and superior lubrication characteristics. For instance, a target of 22 carbon, two branched chains, and 20 unsaturated bonds can be precisely achieved, ensuring that the oil meets all performance standards.

Economic and Environmental Benefits

In addition to the technical benefits, synthetic oil offers economic and environmental advantages. The consistency and quality of synthetic oil reduce maintenance costs and extend the life of engines, which in turn reduces the frequency of oil changes and the environmental impact of oil disposal. Furthermore, synthetic oil's lower emissions and reduced impact on climate change make it a more sustainable choice for the future.

Conclusion

The development of synthetic oil addressed the limitations of natural petroleum by offering a more controlled, consistent, and environmentally friendly alternative. Its ability to be refined precisely and its lack of impurities, such as sulfur, make it an ideal choice for modern engines. As the demand for high-performance and eco-friendly vehicles continues to grow, synthetic oil is likely to play an increasingly important role in the global energy landscape.
