The Effect Of Ultrasonic Vibrations And Catalyst Particle Size On The Decomposition Of Cumene, John F. Pietranski
Theses
The effect of ultrasonic vibrations on the vapor phase decomposition of cumene to benzene and proplyene was investigated using silica-aluminum as the cracking catalyst.
The system consists of a tubular reactor with a 4 inch long catalyst chamber made from 1 cm. diameter stainless steel tubing. The catalyst bed was irradiated from above by means of an ultrasonic horn.
The reactor was run at temperatures of 850 to 950°F., frequencies of 26,000 and 39,000 Hz, with a power innut of 0.30 watts/cm.2 . Feed rates of 100 to 300 gms./hr. and catalyst particle sizes of 0.0209 to 0.358 cm. …
