In the case of C02-selective membranes in precombustion processes, the fuel heating value remains at the high-pressure retentate side (H2 and unconverted fuel) in the WGS separation process. The power-cycle efficiency for natural-gas-fuelled GTCC including C02-selective membranes in the WGS reactor appears less pressure dependent compared to hydrogen-selective membranes, due to the lower amount of C02 produced in the MSR + WGS reactions [24]. A relative simple simulation for precombustion capture made (based on C02/H2 selectivity of 50) [24], suggests that... 

Natural gas steam reforming process is an ideal candidate for hydrogen selective membrane integration tanks to its high reaction endothermicity and the fast kinetics leading to equilibrium condition inside traditional reactors. 

Many efforts devoted to the development of membrane competitive applications by the most prestigious research centers worldwide attest the strategic importance and the potentiality of membrane reactors for the industry. The scientific production dealing with selective membrane reactors is growing exponentially as reported in Chap. 2, 750 papers on membrane reactors have been published in 2009, of which 220 on Pd-based membranes. The main processes in which R D departments are focusing the attention are those devoted to hydrogen production, for which two configurations are imder study ... 

Erika Lollobattista is a Chemist, actually working in the R D group of Processi Innovativi Sri, a company owned by Tecnimont KT SpA, Rome, Italy. She received his Master degree in Chemistry in 2003, from the University of Rome La Sapienza . Most recent work includes the study and development of hydrogen selective membranes applied in methane steam reforming and water-gas shift reactors. She managed/attended a number of European research projects in the field of membranes application. 

In configuration 1, the reformer and membrane module (RMM) where hydrogen selective membrane is assembled in separation modules applied downstream to reaction units so that the process scheme is composed by a series of reaction-separation units (staged membrane reactor architecture)... 

This chapter presents a methodology to assess the economics of membrane reactors when applied to power and hydrogen production. From the many types and applications of membrane reactors discussed in previous chapters, this chapter wiU investigate only hydrogen selective membranes for power and/ or hydrogen production with CO2 capture this type of membrane is considered the most promising application and with the potentially highest impact.

The so-called fluidized bed membrane reactor (FBMR) is obtained by immersing bundles of hydrogen-selective membranes into a gas—solid fluidized suspension (see Figure 3.7) (Gallucci et al., 2008a, 2008b).
