Conversion rate of diene value in gasoline
Thread Content
Is it true that the higher the conversion rate of diene value in gasoline, the better?
Gasoline conjugated dienes tend to form gums on their own, and they also accelerate the oxidation of other hydrocarbons, thereby affecting the stability of gasoline. Therefore, it is necessary to effectively remove conjugated dienes from gasoline; that is, without compromising its octane rating, the lower the diene content, the better, and the higher the conversion rate of these dienes, the better.
As mentioned upstairs, it’s correct that while maintaining the unsaturation of olefins, the fewer dienes there are, the better. But it seems that the current catalysts do not yet have such excellent performance
A high conversion rate of the diene value, combined with an increased hydrogen-to-oil ratio and a reduced reaction temperature, can effectively minimize octane number loss
Personally, I think setting it too high wears down the catalyst’s lifespan; a suitable value is sufficient.
