Introduction
Aromatic hydrocarbon (AHC) is a very important resource in our daily life. It is widely used in fuel, other organic chemicals and materials. AHC can also be used to produce gasoline and other products through off-gas reforming and catalytic cracking processes. With the rapid development of petrochemical industry, the amount of aromatic hydrocarbon has greatly increased, and the utilization rate has greatly increased.
Due to its wide adaptability and fast reaction, the aromatic carbonization process has been widely used. Aromatic hydrocarbon carbonization is a process of carbonizing and refining aromatic hydrocarbon raw materials to reduce viscosity and obtain aromatic hydrocarbon products with certain stability, which can be widely used in petrochemical industry.
Aromatic hydrocarbon carbonization process
Aromatic hydrocarbon carbonization process is an important technology of aromatic hydrocarbon cracking. The raw material of this process is aromatic hydrocarbon, and the product is aromatic hydrocarbon. There are three main steps in the carbonization process: pyrolysis, desulphurization and condensation.
In the process of pyrolysis, the aromatic hydrocarbon is heated to a high temperature in the reactor and decomposed into light hydrocarbon and other substances such as sulfur, nitrogen and chlorine.
Desulphurization is the process of removing sulfur, nitrogen, chlorine and other harmful substances from the carbonized aromatic hydrocarbon. This step is necessary to improve the quality of the product.
The condensation step is the last step in the aromatic hydrocarbon carbonization process. In this step, the hydrocarbon molecules collide and recombine to produce high-quality aromatic hydrocarbon products.
Product Quality
The quality of the aromatic hydrocarbon products obtained from the thermal cracking process depends on the pyrolysis temperature, residence time, feedstock type and humidity. The pyrolysis temperature is the most important factor that affects the quality of the product.
At higher pyrolysis temperatures, aromatic hydrocarbons can efficiently produce light hydrocarbons such as ethylene, propylene and butene, as well as other products such as coke. The residence time is also an important factor influencing yield. Higher residence time results in higher yields of light hydrocarbons, but also tends to produce more coke. The feedstock type also affects the quality of the product. If the aromatic hydrocarbon content in the feedstock is high, the light hydrocarbons can be efficiently produced, but it is easy to produce coke.
Conclusion
Aromatic hydrocarbon carbonization process is a widely used technology in the petrochemical industry, which can efficiently produce light hydrocarbons such as ethylene, propylene and butene. The quality of the products obtained by this technology depends on the pyrolysis temperature, residence time, feedstock type and humidity. Therefore, it is very important to control these conditions to obtain high-quality products.
