Olefin content in stabilized gasoline
Thread Content
What factors have the greatest impact on the olefin content in stabilized gasoline? In our company’s two catalytic units, the olefin content is 31% in one unit and 38% in the other – there is a significant difference
31 Is that something that keeps running and adding agents continuously?
Reaction temperature, whether the catalyst is the same.
Different reaction patterns and the residence time of the feed oil in the riser result in variations in the olefin content of the product; this is also the fundamental reason for the differences among various catalytic units and their respective yields.
The catalyst usage time for the two devices is different, right?
If the raw materials are the same, the operating conditions are the same, and the equipment is of the same type, then it is the catalysts and additives used that differ; therefore, depending on the desired product, different measures are taken by the equipment. OP, your criteria are too simple.
Haha! I want to say the same thing! There are too many influencing factors! Raw materials, catalysts, additives, reaction temperature, pressure, device type, and so on!
Mainly the types of catalysts and additives, the amount added, and the influence of reaction conditions (operational parameters)
The catalyst with number 31 has a slightly higher activity, around 64, while the one with number 62 has an activity around 62; the latter does not experience catalyst degradation
The catalyst has high activity, strong hydrogen transfer reaction, and low olefin content
