Does an increased proportion of fuel additives raise the octane number?
Thread Content
For diesel hydrogenation feedstocks, namely Cuaiji and Changji, if the proportion of Cuaiji is increased while keeping the amount of Changji constant, will the cetane number of the refined diesel increase or decrease? Why pinch?
With all other operating conditions unchanged, the more catalytic fuel is used in blending, the lower the cetane number will be; the cetane number of the catalytic fuel component is very low!
Reduce it; catalytic diesel already has a low cetane number, and if more of such diesel is produced, there’s no need for any modification
Lower! There are many polycyclic aromatic hydrocarbons that accelerate combustion, and the cetane number is low
It decreases; catalyzed diesel has a relatively low cetane number.
The cetane number of refined diesel decreases, and the cetane number of catalyzed diesel is low.
