摘要：

The major potential lines of enhancing efficiency and economy of membrane units for producing special-purity (super-purity) hydrogen from methane are mathematically analyzed. It is shown that one of the potential ways of enhancing efficiency is improving the process flow structure and modes of operation of the unit with a view to increasing hydrogen concentration in the gas phase prior to membrane separation. In another case, the efficiency of special-purity hydrogen production can be enhanced in the simple high-temperature converter-membrane unit system by combining membrane extraction of hydrogen with catalytic conversion of methane and selection of process parameters. © 2011 Springer Science+Business Media, Inc.
