Difference Between Thermal Cracking 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.

Why is catalytic cracking better than 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.

Is catalytic cracking thermal decomposition?

Catalytic cracking is a conversion process that can be applied to a variety of feedstocks ranging from gas oil to heavy crude oil and residuum. ... The carbonaceous deposit arises from the thermal decomposition of high-molecular-weight polar species (asphaltene constituents and resin constituents) in the feedstock.

What are the two 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 cracking explain 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 are the conditions needed for cracking?

Cracking

• Thermal cracking uses harsh conditions like high temperature and high pressure.
• It breaks the alkanes into a high percentage of alkenes and comparatively few alkanes.
• Thermal cracking is done at about 1,000 degrees Celcius and 70 atm pressure.

What is required for catalytic cracking?

The catalytic cracking process involves the presence of solid acid catalysts, usually silica-alumina and zeolites. The catalysts promote the formation of carbocations, which undergo processes of rearrangement and scission of C-C bonds.

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?

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.

How is cracking done by thermal decomposition?

Thermal cracking is a type of chemical reaction that uses heat to break down long chain molecules into smaller, more reactive, and therefore potentially more useful, molecules. ... The solution is to crack these large alkane molecules to produce the smaller molecules of the fractions that are under produced.

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 the process of cracking?

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 importance of cracking?

Cracking is important for two main reasons: It helps to match the supply of fractions with the demand for them. It produces alkenes, which are useful as feedstock for the petrochemical industry.
