Gasoline loses a lot of hydrogenation octane number
Thread Content
Our factory uses ExxonS catalysts for gasoline hydrogenation, and recently we have experienced a significant drop in octane rating, which has fallen to 2.9. The method of lowering the reaction temperature was also tried, but it was ineffective. Are there any other methods?
The cutting ratio of the pre-cutting tower needs to be set properly; otherwise, when light components enter the reactor, there is significant loss of olefins, and of course the octane rating also decreases as a result····
When dealing with the manufacturer, it’s very important to adjust the cutting point.
Could you clarify the specific details? Adjustments are generally made in the following aspects: 1. Appropriately increase the cutting ratio ； 2. Increase the reflux ratio appropriately ； 3. The raw material has a high sulfur content, resulting in significant loss of octane rating; the ratio of the raw materials can be adjusted accordingly ；
In principle, while ensuring the product remains qualified, it is necessary to increase the cutting ratio and lower the reactor temperature; you can conduct tests before and after the reactor to see exactly how much loss occurs Also, take a good look at your process
What are the approximate sulfur contents in the raw materials and products? If the operating parameters of the device remain stable, check the raw materials to see if the sulfur content has increased Increased olefin content?
1. Load issue 2. Cutting ratio 3. Hydrogen temperature (excessive carbon monoxide) 4. Reaction temperature 5. Properties of raw materials
1. Increase the cutting ratio appropriately； 2. Increase the reflux ratio appropriately ； 3. The raw material has a high sulfur content, resulting in significant loss of octane rating; the ratio of the raw materials can be adjusted accordingly ； 4. Reaction temperature: 5. Hydrogen temperature:
I’m sorry, I don’t understand what the cutting ratio means. Could you explain what it is compared to?
