Switching from processing straight-run gasoline to processing catalytic reformate did not yield good results
Thread Content
We have a 350,000-ton gasoline hydrogenation unit here; it was used to process naphtha some time ago and then switched to processing catalytic gasoline, but the desulfurization effect after 12 hours was very poor. Why is this?
There is a significant difference in the total sulfur content of the two raw materials; the form in which sulfur exists in catalytic gasoline requires further investigation
The total sulfur is roughly the same; it seems that a deeper treatment is needed. Thank you
Try increasing the reaction temperature; catalytic gasoline contains more olefins, which results in higher hydrogen consumption for saturation, and the temperature rise is greater compared to normal-pressure gasoline. Try using cold hydrogen
Straight-run gasoline has a low content of olefins, and the reaction is not intense. It is generally used as a carrier for sulfurized oil; catalytic gasoline is usually processed in this way. Attempting to increase the depth of the reaction should lead to a more significant desulfurization effect
