pre-hydrogenation
Thread Content
What is the actual use of the pre-hydrogenation system?
It involves hydrogenation to remove impurities such as sulfur, nitrogen, and chlorine from the raw material
Transfer the sulfur from the light components of gasoline to the heavy components; in this way, after the separation of light and heavy components, the sulfur content in the light components is low, and the relative extraction amount increases, which helps to reduce octane number loss. Additionally, dienes are not fully hydrogenated to form relatively stable products such as monoenes, thereby preventing coking of dienes and similar compounds during subsequent hydrodesulfurization processes.
Converts unsaturated hydrocarbons into saturated ones to prevent coking and overheating in subsequent processes.
What is the relationship with hydrocracking?
I agree with the statement that it converts unsaturated hydrocarbons into saturated ones, preventing coking and overheating in subsequent processes. “”
The pre-hydrogenation data refinement catalyst has very low cracking capacity; it is used for hydrocracking, primarily as a cracking agent. The amount of cracking is very large
What is the next step after the raw materials are pre-hydrogenated? Which device should it be sent to?
Diene compounds are saturated to form relatively stable products such as monoenes, thereby preventing coking of dienes and similar compounds during subsequent hydrodesulfurization processes, and converting small-molecule sulfur into large-molecule sulfur
1. Light component sulfur transfer； 2. Diene saturation to prevent coking
