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: Hydrocarbon vapors are passed at approximately 400C (750F) over a metallic catalyst (e.g., silica-alumina or platinum); the complex recombinations (alkylation, polymerization, isomerization, etc.) occur within seconds to yield high-octane gasoline.

• Weiss-Hortala, NZIHOU A., Catalytic cracking of ethylbenzene as tar surrogate using pyrolysis chars from wastes.

• Catalytic cracking and fluid coking units below this threshold must use the required flow and gas monitors if they are in- place, but may use engineering estimates for determining CO2 emissions if the required flow and gas monitors are not in place.

• Wang, Catalytic cracking of large molecules over hierarchical zeolites, Chem.

• Catalytic cracking, coking, and other conversion units, referred to as secondary processing units, add to a refinery’s complexity and can actually increase the volume of its output.

• Catalytic cracking is selected to be used rather than thermal cracking as this method does not required as high temperature compared with thermal cracking which could save operating cost in this system and also the cracking reaction increases the yield of improved quality products at a lower temperature.

• To determine whether your facility is regulated by this action, you should examine the applicability criteria in 40 CFR 63.1561 of the NESHAP for petroleum refineries: Catalytic cracking units, catalytic reforming units, and sulfur recovery units.

• 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 is chosen as the hot gas clean up in the laboratory scale gasification process in this research as it is considered to be one of the most promising methods for tar elimination and does not generate wastewater (Saxena et al.

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