Applications

Accelerated video showing the enhanced adsorption rates of methylene blue onto activated carbon using a rotating bed reactor (RBR) compared to a stirred tank reactor (STR). The RBR decolourized the solution almost twice as fast, did not create any visible fines and required no filtration.

Poster on study of catalyst recycling during esterification and transesterification reactions with immobilized lipases in rotating bed reactors. Data from several laboratories showed that no attrition or grinding occurred and that no filtration was necessary between reaction cycles. The production capacity was estimated to 50 kilograms per gram of catalyst thanks to the high catalyst stability.

Illustrative video showing how a phenolic colourant is deprotonated and extracted from an organic to an aqueous solvent. Using SpinChem® RBR in a flower-baffled reaction vessel created fine emulsion droplets resulting in effective phase-transfer between the two liquids and the solid phase.

Comparison of rotating bed reactor (RBR) technology and fixed bed reactor (FBR) column during activated carbon decolourization. The more efficient use of the adsorbent with a SpinChem® RBR enabled completion of the process within 40% of the time at the same material amount or allowed reduction to 50% material while still being able to finish the process within the same time as the FBR.

Convenient transfer hydrogenation catalysed by palladium-containing beads was performed using a SpinChem® rotating bed reactor (RBR). The set-up resulted in high product conversions throughout more than 10 consecutive batches without any need for filtration to recycle the catalyst.
