Prasad Ravi, Gottzmann Christian Friedrich: Reactor comprising a ceramic membrane for carrying out endothermic reactions and process for providing heat to endotermic reactions. Praxair Technology, March 8, 2000: EP0984500-A2 (34 worldwide citation)

Syngas, a mixture of hydrogen and carbon monoxide, is an intermediate in the conversion of methane to liquid fuels. For certain applications, it is desirable to maintain an H2/CO molar ratio of about 3. This molar ratio is achieved by steam reforming of methane in accordance with: CH4 + H2O -> 3H2 + ...
