Abstract

Air Products and Chemicals and its partners are developing Ion Transport Membrane (ITM) technology for the production of hydrogen and carbon monoxide (synthesis gas or syngas). The ITM Syngas process is a breakthrough technology that combines air separation and high-temperature synthesis gas generation processes into a single ceramic membrane reactor, with significant savings in the capital cost of synthesis gas production. Because synthesis gas is a feedstock for a range of different processes, ITM Syngas represents a technology platform that has numerous applications, such as hydrogen, clean fuels and chemicals. ITM ceramic membranes are fabricated from non-porous, mixed-metal oxides and operate with exceptionally high oxygen flux and selectivity when exposed to an oxygen chemical potential gradient at high temperatures. This paper describes the development of the ITM Syngas ceramic membrane and the development of the reactor design, resulting in stable oxygen fluxes at our commercial target.
