Metallic membranes and membrane reactors have become very popular tools for several process intensification strategies. This is being well recognized at European level, where several projects have been granted in the course of the last three Framework Programs on both membranes as separation tools and especially membrane reactors as process integration tools. This chapter, although not exhaustive (especially because of confidentiality issues), gives a good overview of the recent results of several EU-funded projects. It is worth noting that, apart from these projects, each country has also granted research projects on membrane reactors. These are not discussed in this chapter, although many results have already been reported in other chapters.
