The effect of temperature on olefin saturation
Thread Content
Dear seniors: In gasoline hydrogenation, what changes occur in the olefin content when the temperature of the selective hydrogenation reactor is increased? Is it the increase in temperature that leads to an increased hydrogenation of olefins, thereby reducing their content? ?
At higher temperatures, olefins are more readily saturated, resulting in a lower content; however, rising temperatures cause significant losses in octane rating. Keeping the temperature within an appropriate range, with the olefin content kept below 35%, should be sufficient. I’m not sure if there have been any changes in the current guidelines regarding olefin control
As the temperature rises, the degree of hydrogenation increases; the increased saturation of olefins leads to further temperature rise and a decrease in octane rating. When the olefin content in the reformed fraction’s hydrogenation section is low, the impact on octane number is minimal
