Catalytic cracking definition

Catalytic cracking means a refinery process of breaking down larger, heavier, and more complex hydrocarbon molecules into simpler and lighter molecules. Catalytic cracking is accomplished by the use of a catalyst.

Examples of Catalytic cracking in a sentence

• Catalytic cracking is carried out over acid microporous sieves, being HZSM-5 zeolite the most studied due to its shape selectivity that maximizes the olefin production.

• Technical process designations substantiate individual process characteristics: • Pyrolysis: allothermal (with external energy supply) process excluding oxygen and air.• Catalytic cracking: allothermal catalytic process.• Hydrocracking: allothermal, catalytic process with the addition of hydrogen.• Gasification: autothermal process (without external energy supply) by partial oxidtion using an additional gaseous reactant.

• Catalytic cracking uses catalysers that, at the same temperature, allow a deeper and more selective transformation of fractions that could be heavier.

• Catalytic cracking is similar to thermal cracking except that catalysts facilitate the conversion of the heavier molecules into lighter products.

• Finally, the innovation of Hydroc- racking replaced Catalytic cracking via improved efficiency and environmental effects (Lakhani, 1975).

• Catalytic cracking produces the same products and by-products as conventional pyrolysis; however, the qualities and quantities of products are different and can vary depending on the catalyst used.

• Catalytic cracking of polyethylene over Al-Silica MCM-41 molecular sieve.

• Catalytic cracking of vacuum gasoil was performed in a Microactivity Test Unit following the procedure described in the literature [30, 32].

• Catalytic cracking of vegetable oils to produce biofuels has been studied [30].

• Catalytic cracking of n-hexane over ZSM-5 zeolite catalysts was carried out using a fixed-bed reactor at a reaction temperature of 823-923 K under N2 at atmospheric pressure.
