Abstract:Ultrasonic pretreatment of gel composition followed by
hydrothermal
synthesis produces the nanocrystallite zeolite beta (ZB) with crystal
sizes of 10.3, 22.6, and 9.1 nm for ZB-1, ZB-2, and ZB-3, respectively.
The effect of ultrasonic pretreatment and the (SiO2/Al2O3) ratio of gel composition on physical, textural
properties, and also on the catalytic activity of ZB catalysts with
increasing time on stream (TOS) was investigated. The specific surface
area and mesopore volume for ZB-1, ZB-2, and ZB-3 are 438, 3… Show more
