Pd-membranes on their Way Towards Application for CO2-capture

Abstract

Pd-membranes in combination with water gas shift (WGS) reactors are considered as a cost and energy efficient technology for CO2 capture in natural gas or coal-fired power stations. An important step towards realization of a full-scale membrane reactor is the demonstration of a scaled-down version. This paper describes the realization of a scaled-down membrane module, which is able to generate a hydrogen flux of approximately 12 Nm3/m2.hr at a hydrogen recovery of 95% and an operating temperature of 400 °C under 30 bar of NGCC-gas composition as feed stream and 6 bar N2 sweep stream.
