Abstract

Combinatorial methodology for zeolite membrane development is discussed. Zeolite membrane is now attracting attentions as an energy-saving separation apparatus via pervaporation and/or vapor permeation, but sometimes it suffers performance (flux and/or separation factor) deterioration due to lack of chemical stability. We separate the development scheme into three steps – i) zeolite selection via chemical affinity and stability evaluation in powder applying combinatorial methodology, ii) membrane preparation for thus selected zeolite species, and iii) their evaluation in parallel manner. We have successfully developed hydrophilic zeolite membranes with tolerance against acidic environment. Thus developed zeolite membranes were successfully applied esterification reaction from a stoichiometric mixture of a carboxylic acid and an alcohol by assisting equilibrium shift via direct pervaporation from crude reaction solution.
