Reactivation of partially deactivated catalyst employing ultrasonic energy |
摘要 |
A solid catalyst composition which has undergone a partial loss of catalytic activity due to the accumulation of reaction product residue is treated in a chemical conversion process reaction zone in the presence of feedstock(s) with ultrasonic energy of a magnitude and a duration sufficient to restore at least a significant percentage of the lost activity.
