Franz et al. [93] developed a palladium membrane micro reactor for hydrogen separation based on MEMS technology, which incorporated integrated devices for heating and temperature measurement. The reactor consisted of two channels separated by the membrane, which was composed of three layers. Two of them, which were made of silicon nitride introduced by low-pressure chemical vapor deposition (0.3 pm thick) and silicon oxide by temperature treatment (0.2 pm thick), served as perforated supports for the palladium membrane. Both layers were deposited on a silicon wafer and subsequently removed from one side completely...

Fumeaux et al. [1987] used porous alumina membrane reactors to hydrogenate ethene to form ethane at 200X with Ft or Os as the catalyst impregnated in the alumina membranes. Conversion to ethane was detected but no data was provided. Suzuki [1987] tested porous stainless steel and nickel-aluminum alloys as membrane reactors for hydrogenation reactions.

Assessment of Natural Gas Splitting with a Concentrating Solar Reactor for Hydrogen Production, April 2002. 

Parallelly a simulation has been started to formulate a flow sheet for the cycle operation. The IS process and its characteristics have been verified. Agreement has been achieved between experimental data and the simulation model. A further improvement of the process is needed to acquire a higher thermal efficiency and to select better structural materials which are compatible on an industrial scale. Further demonstration steps are the employment of a metallic reactor for hydrogen production at a rate of 1 Nm /h and a scale-up process to a 100 Nm /h rate [44]. The IS process is one of the candidates to be connected to the HTTR following the steam reforming system.
