What Is Petrol Made Of? – Gasoline comes from crude oil underground. As most people know, oil itself is formed over hundreds of millions of years from the remains of prehistoric plants and animals, crushed and burned by the action of the earth. This is where the term ‘fossil fuel’ comes from. Now hundreds of millions of years later, this rich resource helps drive the world’s greatest achievements, and it’s proud to play its part.
In our short time using ‘black gold’ we have seen countless applications, but the places we have are few. It therefore takes a leading role in providing better, smarter solutions to the oil and gas industry. Now thanks to digital technology it is a digital process. With advanced sensors closely linked to Predix’s industrial cloud analytics software, the industry is helping to extract oil from the ground with an unprecedented level of control and monitoring. And only one of the three iCenters in the world designed to monitor this flow of information for the oil and gas industry is here in Malaysia, located in Kuala Lumpur. Just 1% efficiency savings can bring $32.3 trillion in savings to the oil and gas industry. But to understand the complexity, we need to understand everything that turns oil into the fuels that make up our world today.

Midgley was a research assistant to Charles Kettering, and the two were responsible for adding tetraethyl to gasoline, an innovation that would have a lasting legacy—though perhaps not in the way they initially imagined.

Before we discuss the finer points of Kettering and Midgley’s proposals, some general background information on gasoline (gasoline to our American readers) is probably in order. Gasoline, like diesel, is extracted from crude oil. However, both differ slightly in their design and usage. They are obtained from crude oil by fractional distillation, where the oil is heated until it boils and melts, then fractions of different boiling points are removed. Gasoline consists of parts whose boiling point is between 35 and 200 degrees Celsius, while gasoline has a boiling point between 250 and 300 degrees Celsius.
Both gasoline and diesel are made from mixtures of hydrocarbons—compounds, not surprisingly, that contain only carbon and hydrogen. Gasoline consists of hydrocarbons with chains between five and twelve carbon atoms long, while diesel chains are slightly longer at ten to fifteen atoms. Each liter of diesel has more energy than gasoline and it is a more efficient fuel even though it is more expensive.
Gasoline and diesel engines work in different ways. In gasoline engines, the engine takes in both fuel and air, the piston moves it, before the spark plug ignites the fuel. The combustion reaction that takes place produces energy, and the engine emits the waste gases that result from this reaction. In diesel engines, air is admitted only at the beginning of the process, and only after this air is compressed is the fuel injected. Diesel engines do not use spark plugs to trigger the combustion reaction – instead, the fuel itself is ignited by the heat generated by the high pressure used in diesel engines.
In gasoline engines, early ignition becomes a problem. Because the fuel is injected early in the process, fuel combustion can sometimes end during the process, before the spark ignites the fuel at the right time. This is known as prevention, and can cause something called engine knock. Knock occurs when the peak of the combustion reaction does not coincide with the stroke of the engine piston. This can cause a real knocking or knocking sound, and can damage the engine – so that’s something we want to avoid.
In & Out Petrol
In order to keep the engine from exploding, scientists have added various additives to the fuel over the years. You’ve probably come across a fuel’s octane rating before – it’s a measure of how well the fuel prevents knocking problems. It refers to two compounds, isooctane and n-heptane. Isooctane is given a standard octane rating of 100, while n-heptane is given a value of 0. The higher the ratio, the better the fuel prevents knocking. Numbers between 0 and 100 refer to mixtures of isooctane and n-heptane; for example, a fuel with an octane rating of 95 will have the same ‘resistance’ as a mixture with 95% isooctane and 5% n-heptane.
Note that this is not the same gasoline that actually contains only isooctane and n-heptane, as the gauge only compares gasoline with this blend. It is also possible to get octane ratings above 100 because there are other compounds that are better at preventing knocking than isooctane. An example is benzene, which has an octane rating of 101.
Knocking is a problem that car manufacturers have been trying to solve for decades. As automobile engines became more powerful in the 1920s, there was an increasing need for fuel additives that could reduce knocking. Kettering and Midgley seemed to hit on the perfect solution; a compound called tetraethyl lead proved to be very effective in reducing knocks, and had the added bonus of being patented. It can be added to gasoline along with 1, 2-dibromoethane, which can react with lead and prevent it from being injected into the engine.
Surprisingly, Kettering, Midgley and their colleagues did nothing in the way of research on the potential health effects of tetraethyl before the release began. This would be unthinkable today, but it is all the more interesting because the effects of lead poisoning were well known at the time, although it was not fully understood that even small exposures were still cause for concern. Many countries had banned basic white paints in the early 1900s due to concerns about lead poisoning – although the United States did not do so until 1978 in particular.

Kettering and Midgley should at least be aware of the potential negative associations, as their additive was advertised by General Motors as ‘Ethyl’, with no mention of its leading component. Midgley himself was forced to resign at one point due to mild lead poisoning, but he apparently had faith in the safety of the compound.
It is worth noting that there was no initial recall of the addition of tetraethyl to gasoline. Workers at a factory producing this material began to experience severe symptoms – falls, convulsions, unconsciousness, and the need for hospitalization. Many workers died as a result, and it wasn’t long before tetraethyl tetraethyl was blamed. Later, many cities banned the sale of gasoline containing tetraethyl lead, and its production was suspended pending a government investigation.
You’d think it would, but General Motors had a hard time finding such an anti-cookie connection, and they weren’t willing to throw away the money they had for development. They say no viable alternatives are available, although documents discovered later show that Kettering was, at the very least, fully aware of other additions being explored by competing companies.
A government investigation found, from a hasty and limited test with erroneous results, that the addition of tetraethyl to gasoline was unlikely to pose a risk to public health, and that its production and sale could resume. However, they noted in their brief comments that their results were met with criticism, and that future use of the vehicles may still cause health problems. They concluded that further investigation of the findings is necessary, and specifically stated, “the committee is of the opinion that this investigation should not be completed.”

Unfortunately, failure is exactly what you did. Only in the middle of the 80s, when they realized that the health problems in the body caused by the lack of radiation, countries began to implement the prohibition of leaded fuel. Its use gradually decreased, many countries completed this phase in 2000; However, in a few selected countries, sealed gasoline is still sold and used. It is clear that the effects of lead produced by engines using leaded fuel were more serious than Midgley and Kettering thought – high levels of lead in the blood are associated with increased rates of violent crime, although this is still a link . definitely approved.
