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.

A method of chemical conversion comprising the steps of: a) providing a filter element comprising a composite filtration medium having an upstream surface and a downstream surface, said composite filtration medium including a first layer comprising a porous fibrous filtration layer and a second layer consisting essentially of one or both of insoluble enzyme particulates and insoluble particulates comprising an enzyme, said second layer being located on the upstream surface of said first layer, and b) allowing a moving reaction solution to impinge upon the upstream surface of said filtration medium of said filter element for a time sufficient to effect chemical conversion, said filter element comprising said insoluble enzyme particulates as catalyst, and allowing said moving reaction solution to pass through said filtration medium at a flux rate of at least 0.01 cm/min.
