Recommended Mixing Equipment For Catalytic Slurries

Charles Ross Feature

Catalytic slurries consisting of solid catalysts and support materials suspended in a liquid medium are commonly prepared in batch tanks agitated by low-speed mixers such as propellers, anchor paddles and pitched blade impellers. These devices can sometimes suffer from long cycle times and inadequate dispersion especially in large batches.

One alternative solution is to introduce the dry ingredients via sub-surface injection under high shear conditions. Technologies like the Ross Solids/Liquid Injection Manifold (SLIM) offer a more practical method of wetting out powders and quickly achieving the desired particle size distribution in high percent solids slurries.
