Can too high a nitrogen content have an impact?
Thread Content
Seek guidance from experts! What are the consequences of high prices for gasoline and its raw materials, and what impact does this have on refined petroleum products? _?
If denitrification is incomplete, the nitrogen content in the product will be high

The nitrogen content in finished gasoline is generally very low, and the nitrogen present in it exists mainly in the form of basic nitrogen; this has no significant impact on the use of the finished gasoline. Perhaps the levels of nitrogen oxides in exhaust gases might be slightly higher, as the proportion of nitrogen that is converted into nitrogen oxides during combustion is low. During the refining of petroleum products, nitrogen compounds in gasoline have a significant impact on refinery catalysts; the basic nitrogen in these compounds neutralizes the acidic sites of hydrogenation catalysts, resulting in a decrease in their activity. Additionally, some nitrogen compounds are components of the gums present in gasoline, and they can contribute to catalyst coking. Therefore, during the hydroprocessing of oil products, it is necessary to strictly control the process conditions and the alkaline nitrogen content of the feed oil in order to ensure a smooth hydroprocessing operation.
The nitrogen content in catalytic gasoline is 50PPM – is that high?
Excessively high nitrogen content in the raw materials can affect catalyst performance, while a high nitrogen content in the product can influence its color
Not high! As long as it’s under 150, there should be no problem! It depends on the requirements!
It affects the stability of gasoline; it will turn black after some time.

Hydrogenating oil products and using catalysts with good denitration properties can remove almost all nitrides. The RN series hydrogenation catalysts from the Petrochemical Science Research Institute should be an excellent choice.
Can the S-ZORB device remove some of the nitrogen?
