Fabrication & performance study of a palladium on alumina supported membrane reactor: Natural gas steam reforming, a case study

摘要

In this work, a synthetic mixture of natural gas is considered in a steam reforming process for generating hydrogen by using a membrane reactor housing a composite membrane constituted of a Pd-layer (13 mu m) supported on alumina. The Pd/Al2O3 membrane separates part of the produced hydrogen through its selective permeation, although it shows a relatively low H-2/N-2 ideal selectivity (200 at 0.5 bar of trans-membrane pressure and T = 425 degrees C).
