Membrane technology plays a key role in downstream processing separation and purification of several products. Based on this assumption, syngas purification and upgrading techniques through membrane technology are discussed in this chapter. A particular focus has been directed toward the dense metal membranes, which are largely studied for the separation/purification of H2 rich-streams due to their unique H2 perm-selectivity characteristics. Special attention has been dedicated to dense Pd and Pd-alloys membranes, which have been described in deep to highlight their potential when used in membrane reactors, useful to carry out the syngas upgrading through the water-gas shift reaction. Furthermore, a comparison between the syngas upgrading performance by membrane technology and those of other traditional processes such as PSA is presented and discussed.

Abstract
Membrane technology plays a key role in downstream processing separation and purification of several products. Based on this assumption, syngas purification and upgrading techniques through membrane technology are discussed in this chapter. A particular focus has been directed toward the dense metal membranes, which are largely studied for the separation/purification of H2 rich-streams due to their unique H2 perm-selectivity characteristics. Special attention has been dedicated to dense Pd and Pd-alloys membranes, which have been described in deep to highlight their potential when used in membrane reactors, useful to carry out the syngas upgrading through the water-gas shift reaction. Furthermore, a comparison between the syngas upgrading performance by membrane technology and those of other traditional processes such as PSA is presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
