Summary

A study was made of the vibratory densification of a bismuth-molybdenum catalyst (with a corundum filler, taken in a weight ratio of 1∶1). It was found that compared with static compaction vibratory densification enables the pressure to be reduced by a factor of about 100, sharply decreases internal stresses, and ensures greater packing density (4.0 g/cm3 against 3.75 g/cm3 in static compaction). It also leads to a 100% increase in the strength of fine-particle, high-porosity catalyst specimens without adversely affecting their catalytic activity.
