dc.description.abstractIn the hydrogen production, the syngas streams produced by reformers and/or coal gasification plants contain a large amount of H2 and CO needing to be upgraded. To this purpose, reactors using Pd-based membranes have been largely studied as they allow separation and recovery of a pure hydrogen stream. However, the high cost of the Pd-membranes is one of the main limitations for technology scaling up. Therefore, many researchers are now pursuing the possibility to use supported membranes with Pd-alloy layers as thinner as possible. In this work, the upgrading of a syngas stream was experimentally investigated in a water gas shift membrane reactor operated in the high temperature range with an ultra-thin supported membrane (4 micron-thick). The membrane permeance was measured before and after catalyst packing and after reaction (in a total 2100 h of operation). Membrane reactor performance was evaluated as a function of operating conditions like temperature, pressure, gas hourly space velocity, feed molar ratio, sweep gas. A CO conversion significantly higher than the thermodynamics upper limit of a traditional reactor was achieved, even at high gas hourly space velocitys and less than 25% of the reaction volume of a traditional reactor was required for achieving a conversion of 90% of the equilibrium conversion.en
