Trilobe and quadrilobe extruder dies with catalyst adsorption

Can trilobe and quadrilobe extruder dies provide benefits when working with catalysts or products for gas adsorption?

Benchtop laboratory extruders working with small amounts of product play a useful role in the production of extrudate for applications aimed at the study and development of products used for catalysis or gas adsorption.

Small units can be particularly useful where the product is costly, difficult to make, or scarce. The preference is often to work with small amounts of material. Small benchtop units are often useful when trials need to be completed quickly, in the least possible time.

 Researchers often ask us about Caleva's small benchtop extruder, which is an attachment for the Caleva Multi Lab (CML) base unit. These questions include:

• Can the design of the equipment help to increase the Surface Area to Volume (SA/V) ratio in the extruded material (extrudate)?
• Is there a guide to the optimum diameter-to-length ratio of the extrudate fragments that will give the best performance?
• Can we be confident that these results generated from this very small equipment can be repeated when scale-up is required?
