Use the diagram to help you to explain how crude oil is separated into fractions. (i) Explain, as fully as you can, how fractional distillation works. first stage of the process is the production of ethene and another hydrocarbon from diagram below shows an apparatus that can be used to demonstrate cracking in the.
Cracking of decane. There is a greater demand for smaller hydrocarbons than larger ones. decane → octane + ethene. C 10 H 22 → C 8 H 18 + C 2 H 4. The process is as follows: Some of the The crude oil that comes out of the ground is useless on its own. However, once the crude oil is refined, it is used to produce gasoline, diesel fuel, paraffin wax, and even plastics. What is crude oil and how is it turned into so many different things? The answer to the question of crude oil’s multiple uses is fractional distillation and cracking. Fractional distillation and cracking are Cracking converts large alkane molecules into smaller, more useful, alkane and alkene molecules. The alkenes can then undergo polymerisation to make polymers (such as plastics) while the shorter alkanes are typically used for fuel. As you can see in the video opposite, cracking needs a catalyst and a high temperature. Fluid catalytic cracking is a commonly used process, and a modern oil refinery will typically include a cat cracker, particularly at refineries in the US, due to the high demand for gasoline. The process was first used around 1942 and employs a powdered catalyst. During WWII, the Allied Forces had plentiful supplies of the materials in contrast Cracking can be done with high temperatures or with the use of a catalyst. Thermal cracking of crude oil involves heating the heavier distillates (like asphalt) to temperatures over 800 degrees Celsius, which breaks down the hydrocarbon chains. Catalytic cracking uses a catalyst to cause a chemical reaction to break the hydrocarbon chain. Cracking converts large alkane molecules into smaller, more useful, alkane and alkene molecules. The alkenes can then undergo polymerisation to make polymers (such as plastics) while the shorter alkanes are typically used for fuel. As you can see in the video opposite, cracking needs a catalyst and a high temperature. Some of the smaller hydrocarbons formed by cracking are used as fuels (eg large chains are often cracked to form octane for petrol, which is in high demand), and the alkenes are used to make
ConclusionPlenty of room for energy savings is possible insteam cracking. And Catalytic cracking technologiescan lead to energy saving up to 20%. 90% chemical processes already benefits from catalysis, so can steam cracking!

Step 2: Catagenesis (or “cracking”) turns kerogen into petroleum and natural gas This behavior is contrary to what is associated with coal formation. So, the plankton is buried and it turns into oil and gas…but where does it go? Oil can be used in many different products, and this is because of its composition of many

Some of the smaller hydrocarbons formed by cracking are used as fuels (eg large chains are often cracked to form octane for petrol, which is in high demand), and the alkenes are used to make Cracking is used to modify the structural nature of the feedstock (i.e. crude oil). There are several different types of cracking, and all are used - sometimes concomitantly. Thermal cracking, steam reforming, catalytic cracking, etc. Cracking causes the rearrangement of the carbon skeletons to shift the equilbria to the product desired. When the process is done, a heavy, almost pure carbon residue is left (coke); the coke is cleaned from the cokers and sold.

Surprisingly, fracking can be traced back to 1862. will help explain why. What is cracking? Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst. The source of the large hydrocarbon molecules is often the naphtha fraction or the gas oil fraction from the fractional distillation of crude oil (petroleum). Steam cracking is a petrochemical process in which saturated hydrocarbons are broken down into smaller, often unsaturated, hydrocarbons. It is the principal industrial method for producing lighter alkenes (olefins), including ethene (or ethylene) and propene (or propylene) (Figure 3.2).
