Can trilobe and quadrilobe extruder dies provide benefits when working with catalysts or products for gas adsorption?
Bench-top 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 product is costly, difficult to make or scarce, where the preference is to work with small amounts of material or when trials need to be completed in the least possible time.
We are often asked four questions by researchers about our small benchtop extruder that is an attachment for the Caleva Multi Lab (CML) base unit. These are:
- 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 the density, and therefore the pore size and product porosity, of the extrudate be modified by users of the CML equipment?
- Can we be confident that these results generated from this very small equipment can be repeated when scale up is required?
