Technical Discussion on Improving Gasoline Octane Number
Thread Content
Marine enthusiasts, let’s discuss the current technologies for increasing gasoline octane rating Alkylation, aromatization, reforming, isomerization.............. Please participate actively in the discussion. Thank you!!
Alkylation and catalytic reforming seem to be more common; alkylation is used primarily for producing high-octane, clean gasoline. There are gasoline mode and triphenyl mode in reforming, while aromatization doesn’t seem to be as effective at present, compared to alkylation and reforming
The upcoming National VI standard is likely to be a time when alkylation and isomerization play a significant role. Otherwise, how can olefins and aromatics lower it?
On January 1, 2017, Beijing began to implement its local standards! !
Aromatization, including the aromatization of tetraene compounds, has been largely discontinued due to poor efficiency; some processes have been converted to alkylation instead； Naphtha aromatization is widely used in the Shandong region, but the National VI standards for gasoline require a reduction in the aromatic content, which presents poor prospects; therefore, naphtha isomerization is a better processing route
Are there any other raw materials? Nowadays, a large amount of naphtha is used as feedstock for continuous reforming. What is the octane rating that can be achieved with gasoline after isomerization?
