Abstract
Effect of pressure swing on diffusion in operating a membrane-immobilized enzyme reactor with pressure swing is investigated. Simultaneous effect of diffusion and pressure swing can be expressed by an enhancement factor. It can be calculated in terms of a factor ψ(=2u0/πkL), where u0 is a permeative flow rate and kLL is a film mass transfer coefficient without pressure swing. Decomposition of H2O2 by catalase was investigated with a thin film system where the diffusion effect is appreciable. Rate of decrease in H2O2 concentration agreed well with the theoretical calculations.
