How do oil companies use cracking isomerisation and reforming to process fractions from crude oil?

Cracking, isomerisation and reforming are usually used to make smaller branched alkanes from the long-chained alkanes. Small branched alkanes can not pack as closely together, so they have weak Van der Waals forces. It means that the products will have low boiling points and are better fuels as they burn more easily.

What is the term given to breaking of long hydrocarbon chains?
cracking (and when done with a catalyst, it's called catalytic cracking)
Is cracking of petroluem fraction a physical or chemical change?
Cracking of petroleum is a chemical process.
What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
What is a process where molecules are split into smaller more useful molecules?
The process is called cracking. The best way of breaking them up uses heat and a catalyst, so we call this catalyst cracking.
What is the process of the breakdown of fats by repeated use and heating?
This is called Cracking.
What is refine oil?
Oil refining is the process of distilling oil and then further reforming, catalytic cracking, hydrofining, blending, and sometimes coking, hydrocracking, alkylating various fractions of the distilled oil.
How does cracking oil fractions form hydrogen?
Magic. :D

How are substnces taken from crude oil?
The refining of crude oil requires separation, distillation, reforming, cracking and related processes to resolve the mixture of components into products.
How does cracking help meet the demands for petrol and other oil fractions?
Cracking, or the splitting of complex molecules into simpler ones, creates a higher yield for petroleum, meaning more can be made out of a smaller amount of oil.
What is cracking and reforming?
Craking is the process whereby complex molecules are broken down into simpler molecules : Example : C36H74 + H2 >> C2H6 + C34H70 Reforming is a process used to convert molecules having low octane ratings into hight- octane liquid products Example CH3(CH2)6CH3 >> CH3C(CH3)2CH2CH(CH3)CH3
What is the Important of cracking?
The importance of cracking is REALLY important ! Due to the presence of the hydrocarbon atoms present in the fossil fuels, the importance is really beneficial for the people who work in the petroleum industry. As a result of this, the fractions of crude oil are collected at different temperatures as biodegradable polymers. =]
Fixed bed catalytic cracking?
A cyclic, regenerable process for cracking of petroleum distillates to produce high-octane gasoline from higher-boiling petroleum fractions; synthetic or natural bead catalysts of activated hydrosilicate of alumina may be used. Also known as Houdry process.
How do you spell cracking?
Cracking is correct, as in cracking an egg.
Why is cracking done?
It is widely used to convert the high-boiling, high-molecular weight hydrocarbon fractions of crude oil to more valuable liquid petroleum gasoline and other products.Answers.com
How is gas made from oil?
Yes,it is a compound made from oil.Answer:"Gas" can refer to gasoline ( a liquid petroleum fuel), fuel gas (a gaseous fuel composed of methane, ethane, propane or butane in various concentrations) or a gas (any material which is not a liquid or solid).Gasoline can either be recovered directly from oil or natural gas wells.It can also be manufactured from petroleum by distillation, or by cracking and reforming of heavy or lighter oil fractionsFuel gas can be recovered from gas wells, recovered from oil wells or manufactured from oil fractions by cracking of heavier components. It can also be made from the anaerobic digestion of organic material.Gases, in general, are not made from petroleum
What is difference between reforming and cracking?
Reforming is a process that involves rearranging the molecular structure of hydrocarbons to produce higher-value products like gasoline or aromatics. Cracking, on the other hand, breaks down larger hydrocarbon molecules into smaller ones, typically to yield products like gasoline or ethylene. Both processes are important in the refining industry to optimize product yields and meet market demands.
