The olefin content in gasoline can exceed 47%, and this is even after the use of additives to reduce olefins. . . . Let’s all analyze this and see – what is the reason for this? What are the solutions?
What are the raw materials used? Generally, paraffin-based materials have a high content of olefins in gasoline, while middle-base materials have the opposite. I have a question: what is the olefin content without the olefin-reducing additive?
The raw material is naphthyl wax oil. . . The normal residue of the blended intermediate base crude oil. . . When it’s not in use, it’s usually around 36%. . . :lol
To address the issue of high olefin content in catalytic cracking gasoline, it is difficult to rely solely on the addition of olefin-reducing additives; instead, appropriate olefin-reduction processes are required, such as the MIP technology developed by Sinopec Research Institute of Petroleum Processing, the auxiliary reactor olefin-reduction technology from China University of Petroleum (Beijing), or the FDFCC technology from Luoyang Petrochemical Engineering Company.
What measures have refineries across the country taken so far to address the issue of excessively high olefin content in gasoline? http://bbs.hcbbs.com/viewthread.php?tid=324232
