purpose of catalytic cracking

Catalytic cracking is widely used in the crude oil refining industry to convert viscous feedstocks into more valuable naphtha and lighter products. As the demand for higher-octane gasoline has increased, catalytic cracking has replaced thermal cracking.

Why is catalytic cracking important?

Catalytic cracking is an important process in the oil industry where petroleum vapor passes through a low-density bed of catalyst, which causes the heavier fractions to 'crack' producing lighter more valuable products. In the petrochemicals industry they are used for producing polyolefins on a very large scale.

Why is catalytic cracking important industrially?

Catalytic cracking is now one of the most important processes practiced in petroleum refining as it allows the use of a much larger fraction of crude oil, converting relatively high molecular weight materials into high octane fuels.

What is the purpose of cracking?

Cracking is a technique used in oil refineries whereby large and complex hydrocarbon molecules are broken down into smaller and lighter components that are more useful for commercial or consumer use. Cracking is a critical stage in the process of refining crude oil.

What is cracking and why is it useful?

Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure and sometimes catalysts. ... Cracking is the most important process for the commercial production of gasoline and diesel fuel.

What are the conditions of catalytic cracking?

Catalytic cracking uses a temperature of approximately 550°C and a catalyst known as a zeolite which contains aluminium oxide and silicon oxide. Steam cracking uses a higher temperature of over 800°C and no catalyst.

What are the 2 types of cracking?

Cracking is primarily of two types – thermal cracking and catalytic cracking. Thermal cracking is further categorised into modern thermal cracking and steam cracking.

What are the advantages of catalytic cracking over thermal cracking?

Catalytic cracking yields a higher quantity of branched-chain, unsaturated, aromatic hydrocarbons as compared to thermal cracking. Catalytic cracking is a better-controlled process than thermal cracking. Petrol obtained by catalytic cracking has lesser sulfur content.

What is the difference between thermal and catalytic cracking?

The main difference between thermal cracking and catalytic cracking is that thermal cracking uses heat energy for the breakdown of compounds whereas catalytic cracking involves a catalyst to obtain products.

What are the two sections of the fluid catalytic cracking process?

What are the two sections of the fluid catalytic cracking process? Explanation: Reactor is used for cracking process and regenerator for regeneration of catalyst. 5. How is the circulation regulated between the reactor and regenerator in FCC?

What is needed for 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 octane is one of the molecules found in petrol (gasoline).

What does cracking mean?

Cracking is the process of breaking into smaller units, especially the process of splitting a large heavy hydrocarbon molecule into smaller, lighter components. The process of breaking down the larger, heavier, and more complex hydrocarbon molecules into simpler and lighter molecules is known as cracking.

Why is broken porcelain used in cracking?

As the porcelain chips are heated the vapour from the paraffin is 'cracked', or broken down into smaller hydrocarbons. ... Cracking them into smaller hydrocarbons makes them easier to use.
