Abstract
Insolubilized enzyme particulates are located on the upstream surface of a filtration layer of a filtering element which can be used in a cartridge filter. Employed in a recycling flow reaction system at relatively high flux rates, the cartridges are useful for conducting catalyzed chemical reactions of dissolved solutes, for example, esterifications, isomerizations, oxidations, reductions, and cyclizations.
