Exwold's expertise in the delivery of active ingredients via granular forms makes catalysis a specific area of interest.
The chemical nature of catalysts is as diverse as catalysis itself, although some generalisations can be made. Proton acids are probably the most widely used catalysts, especially for the many reactions involving water, including hydrolysis and its reverse. Multifunctional solids often are catalytically active, e.g. zeolites, alumina and certain forms of graphitic carbon. Transition metals are often used to catalyse redox reactions (oxidation, hydrogenation). Many catalytic processes, especially those involving hydrogen, require platinum metals.
If you require your catalyst in a granular form, or another bespoke form, we'd like to hear from you.
Typical methods used to process catalysts are compaction, blending, impregnation, coating and sieving.
