What technical modifications are currently required to convert catalytic gasoline to Euro 4 standards?
1. Reduce olefin content. . . 2. Reduce the sulfur content to 50 ppm. . . 3. Generally, a gasoline deep selective hydrodesulfurization unit is required. . . 4. For catalytic cracking, new processes and new catalysts with an olefin content that meets Euro 4 standards must be employed. . . :lol
It is mainly to control the olefin content and sulfur content in gasoline； To meet the Euro 4 standard, processes to reduce the olefin content in gasoline must be employed, as well as advanced hydrodesulfurization units ； Our company plans to replace the DCC unit with a TMP unit this year in order to reduce the olefin content in gasoline, and to install an additional gasoline hydroprocessing unit for more thorough desulfurization beyond what is achieved through gasoline desulfurization.
