The presentation will cover different approaches to the testing of formed catalysts at the lab scale, in particular the concept of a “pellet .. Read more string” reactor. Many of the catalysts handled and used industrially, will be formed to a shape like extrusions, tablets, spheres etc for use in continuously operated reactors. However powdered catalysts used in batch, slurry reactors are also widely used particular for Fine and Specialty chemicals. This presentation looks at a snapshot of catalyst manufacture, some tips on mixing and usage, reactor types and separation and catalyst reuse for subsequent batches. This short presentation attempts to elucidate the whole trouble-shooting field even down to purity of process gases, reactor types and feedstock purity and cost versus its catalyst poison profile. Examples of 3 applications for powdered catalysts are discussed. The rapid growth of biocatalysis research has provided many new technologies, and solved significant problems in chemicals synthesis.
