How can the octane number of naphtha be increased?
Thread Content
I would like to ask everyone: what are the commonly used processes for increasing the octane number of naphtha at present?
Same question,,, please give me some advice,,,,
Blended with MTBE. MTBE octane number 115~
The improvement of naphtha octane number can be considered from two aspects: one is the addition of blending components as mentioned by those above, such as MTBE, aromatics, alkylated oils, and other components with high octane numbers； On the other hand, there are methods of modifying naphtha to produce high-octane components, such as the combined process of light naphtha isomerization and heavy naphtha hydrodesis, as well as processes like naphtha non-hydrodesis. At present, with the upgrade and modification of **National Standard V gasoline, more and more companies are investing in projects for low-temperature isomerization of naphtha.
Two aspects need to be considered: one is the addition of high-octane components such as MTBE, alkylated oils, and heavy aromatics for blending； Another aspect is the modification of naphtha, such as isomerization and aromatization.
Simply adding MTBE doesn’t require much technical skill; low-temperature isomerization of naphtha is the proper approach!
Simply adding additives for mixing doesn’t require much technical skill; naphtha isomerization and cyclodehydrogenation are the proper approaches!
Based on the properties of naphtha, the following methods can be employed: 1. Catalytic reforming 2. Isomerization 3. Blending with high-octane components
