What is cracking explain with example?

The decomposition of a compound by heat in the absence of air is called Pyrolysis. When pyrolysis occurs in alkanes, the process is termed as cracking. For example: Alkanes on heating under high temperature or in the presence of a catalyst in absence of air broken down into lower alkanes, alkenes and hydrogen.

What is cracking and 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. On the other hand, sub-classifications of catalytic methods of cracking are hydrocracking and fluid catalytic cracking.

What is catalytic cracking in chemistry?

Steam or catalytic degradation (cracking) refers to the degradation of a plastic by means of steam or a catalyst. In catalytic cracking solid catalysts effectively convert plastics into liquid fuel, giving lighter fractions as compared to thermal cracking.

What is catalytic and thermal cracking?

Definition. Thermal Cracking: Thermal cracking is the process of breaking down large compounds into small compounds at high temperatures and high pressures. Catalytic Cracking: Catalytic cracking is the breakdown of large compounds into small hydrocarbons using an acid catalyst.

What is meant by cracking describe fluidized bed catalytic cracking?

Fluid Catalytic Cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, olefinic gases, and other petroleum products.

What is fluidized bed catalytic cracking?

Fluid catalytic cracking is the most important conversion process used in petroleum refineries to convert the high-boiling feedstock constituents to more valuable naphtha, olefin gases, as well as other products and is likely to remain predominant in the refining industry for at least another three-to-five decades.

What is catalytic cracking?

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.

What do you mean by catalytic cracking?

Catalytic cracking is a process in which complex hydrocarbons are broken down into simpler molecules. The purpose of catalytic cracking is to break down complex hydrocarbons into simpler molecules in order to increase the quality and quantity of lighter and more desirable products.

What happens in catalytic cracking?

How is catalytic cracking done?

Various methods can be used for cracking, eg catalytic cracking and steam 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.
