  • Separation process using zeolite membrane
    Patent number: 5942119
    Abstract: The present invention is an improvement in a separation process. When molecular sieve membranes are used in a separation process transport flux decays over time. It has been discovered that the presence of hydrogen in the feed stream, permeate stream, or feed stream when present, either alone or in combination, causes a reduction in flux decay.
