Characteristics and technical characteristics of residue catalytic cracking

Cracking is the process of breaking hydrocarbons with large relative molecular mass and high boiling point into hydrocarbons with small relative molecular weight and low boiling point under certain conditions.

Cracking under catalysis is also known as catalytic cracking.

Cracking is a process in which the long-chain hydrocarbons in petroleum fractionation products (including petroleum gas) are broken into short-chain hydrocarbons such as ethylene and propylene at a higher temperature (700 800 or sometimes as high as 1000) than cracking in the petrochemical production process.

Cracking is a deeper type of cracking. The chemical process of petroleum cracking is relatively complex, and the pyrolysis gas generated is a mixture of gas with complex composition, in addition to the main product ethylene, there are propylene, isobutylene, methane, ethane, butane, alkyne, hydrogen sulfide and carbon oxides. After purification and separation, the pyrolysis gas can obtain basic organic chemical raw materials such as ethylene and propylene of the required purity.

At present, petroleum cracking has become the main method for the production of ethylene.

In petroleum refining, whether it is catalytic cracking, hot cracking or coking, the gas containing propylene will be produced, of which the catalytic cracking process produces the most propylene.

1.Petroleum catalytic cracking mainly includes three processes: raw oil catalytic cracking, catalyst regeneration, and product separation.

2.The purpose is to crack heavy oil under the action of heat and catalyst to convert into cracking gas, gasoline and diesel, which is also one of the important processes of petroleum refining.

3.Petroleum is generally cracked, cracking is the petrochemical production process, at a temperature higher than cracking (70 80, sometimes even as high as 1 Huai pure), so that the long-chain hydrocarbons in petroleum fractionation products (including petroleum gas) are broken into ethylene, propylene and other short-chain hydrocarbons in the process of petrochemical production.

The purpose is to crack the heavy oil under the action of heat and catalyst, and turn it into cracking gas, gasoline and diesel, which is also one of the important processes of petroleum refining.

Summary. The basic principle of heavy oil catalytic cracking and viscosity reduction mining in oil reservoirs.

Hello dear, the characteristics of heavy oil catalytic cracking (1) High coke yield. The coke yield of heavy oil catalytic cracking is as high as 8 12 wt%, while the coke yield of distillate catalytic cracking is typically 5 6 wt%. (2) Heavy metal pollution catalysts.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

The main treatment process of soil acid acidification.

Yes, in the catalytic cracking reaction, there are positive carbon ion reactions and thermal cracking reactions, both of which are chemical reactions.

Positive carbon ion reaction is catalytic cracking reaction, which includes cracking reaction, isomerization reaction, aromatization reaction, dehydrogenation reaction, hydrogen transfer reaction, condensation reaction, etc., through the above reaction, the chemical bond of heavy oil is a complex macromolecular organic compound to open to generate small molecule organic compounds, hydrogen and coke, small molecule organic compounds are generally our target products: gas, liquid hydrocarbons, gasoline, light diesel oil and so on.
