How William Burton Invented Modern Gasoline Refining
A 1913 patent by William Burton that describes a thermal cracking process to turn heavy crude oil into usable gasoline for automobiles.
Original patent title: “Manufacture of gasolene.”
A 1913 patent by William Burton that describes a thermal cracking process to turn heavy crude oil into usable gasoline for automobiles. Granted to Standard Oil Co in 1913 with 2 forward citations, and it is now in the public domain.
Coverage
What does this patent actually cover?
The patent describes a method for increasing the yield of gasoline from crude oil by heating heavy oil fractions under pressure. By applying heat and pressure in a closed vessel, the process breaks down larger, heavier hydrocarbon molecules into smaller, lighter ones suitable for internal combustion engines. This thermal cracking process allowed refiners to extract significantly more fuel from every barrel of oil compared to simple distillation.
The gap
What does this patent NOT cover?
- Does not cover catalytic cracking, which uses chemical catalysts to speed up the reaction.
- Does not cover modern hydrocracking techniques that use hydrogen gas to improve fuel quality.
- Does not cover the extraction of crude oil from the ground.
- Does not cover the design of the internal combustion engines that consume the gasoline.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
What made this novel
Burton realized that by keeping the oil under pressure while heating it, he could prevent the liquid from boiling away too quickly, forcing the heavy molecules to break apart rather than just vaporizing.

Why it matters
The bigger picture
This invention was critical to the growth of the early automotive industry. Before this process, gasoline was a byproduct of kerosene production and was often discarded; Burton's method turned it into a primary, high-value product that fueled the mass adoption of the car.

Market context
Who's building on this
Companies in this space
Modern global energy companies like ExxonMobil, Chevron, and BP continue to refine and scale the fundamental principles of hydrocarbon cracking. While the technology has evolved into highly sophisticated catalytic and hydro-processing units, the core objective of maximizing fuel yield from crude remains the same.
Market impact
The patent enabled the rapid expansion of the oil refining industry and provided the fuel necessary to sustain the massive growth of the automotive sector in the 1910s and 1920s. It effectively transformed gasoline from a refinery nuisance into the most economically significant product in the energy market.
